So far, one has to set the "fork" value to both the start and stop
goals. Since they have the same name, sharing them in a global
configuration element does the trick. However, the plugin also supports
auto-detection of the fork value according to other parameters:
typically if an agent or jvm arguments are set, forking will be
automatically enabled. This is a problem since the stop goal is not aware
of that.
This commit transmits the value in a property attached to the
`MavenProject`. That way, the stop goal can retrieve that value and
apply the same defaults. This has the side effect that specifying the
fork value isn't necessary anymore.

Previously, configuring the build-info goal in a pom would result in
Eclipse reporting an error for the pom as it didn’t know if/when to
execute the build-info goal.
This commit adds lifecycle mapping metadata so that the goal is executed
on incremental builds. This ensures that the contents of the generated
file are kept up-to-date, reflecting the latest build time, etc.

Previously, RandomAccessDataFile used a semaphore and acquired it
interruptibly. This meant that an interrupted thread was unable to
access the file. Notably, this would prevent LaunchedURLClassLoader from
loading classes or resources on an interrupted thread.
The previous commit (937f857) updates RandomAccessDataFile to acquire
the semaphore uninterruptibly. This commit adds a test to
LaunchedURLClassLoader to verify that it can now load a resource from
an interrupted thread.

Previously, if mvn spring-boot:run with a forked JVM was killed with
CTRL+C, the run would be considered unsuccessful. This commits updates
the run mojo to consider a forked JVM that exists with 130 (the exit

be successful.
Closes gh-6498
The unpack location is (largely) an implementation detail and the
Repackage Mojo was the only place where it was explicity documented.
Rather than updating the outdated location, this commit removes it
entirely to avoid encouraging people to rely on the location.

META-INF/INDEX.LIST files are pointless in an executable jar and
moving application classes from the root of the jar to
BOOT-INF/classes breaks the index, resulting in an
InvalidJarIndexException being thrown.
This commit updates the Repackager to automatically remove a
META-INF/INDEX.LIST file from a jar file that is being repackaged.
Closes gh-6601
Where possible, code that previously synchronized on this (or on the
class in the case of static methods) has been updated to use an
internal monitor object instead. This allows the locking model that's
employed to be an implementation detail rather than part of the
class's API.
Classes that override a synchronized method continue to declare
the overriding method as synchronized. This ensures that locking
is consistent across the superclass and its subclass.

Previously, if a property name had successive capital letters, the
generated meta-data would clean it in such a way it is defined as a
regular word. For instance a `myFOO` property would be written as
`my-foo` in the meta-data.
It turns out this decision is wrong as the binder has no way to compute
back the name of the property and therefore `my-foo` wouldn't bind to
`setMyFOO` as it should.
This commit updates the meta-data name generation algorithm to properly
identify such cases: `myFOO` now translates to `my-f-o-o`. While the
generated name is a bit ugly, it now provides a consistent binding
experience.

This commit improves the performance of JarURLConnection. There are two
main changes:
Firstly, the way in which the spec is determined has been changed so
that it’s no longer necessary to create an absolute file. Instead,
the JarFile’s pathFromRoot is used to extract the spec from the URL
relative to the JarFile.
Secondly, the number of temporary Objects that are created has been
reduced, for example by tracking an index as we process a String
rather than creating a new substring for each iteration.
See gh-6215
JarURLConnection is very performance sensitive. The change in 3772d9f
meant that every JarURLConnection would create a FilePermission,
irrespective of whether it was actually used.
This commit updates JarURLConnection to create its FilePermission
lazily. When there is no security manager a permission will no longer
be created at all.
Closes gh-5411
See gh-6215
Previously, JarURLConnection assumed that that URL with which it was
created would contain the absolute path of the underlying jar file.
This meant that when it was created with a relative URL, it could fail
to find an entry or throw a StringIndexOutOfBoundsException.
This commit updates the logic for normalizing the input URL so that
both absolute and relative URLs are supported.
Closes gh-6109
This commit detects case where the same set of keys are exposed several
times and prevents the compilation to complete. Previously, duplicate

Update TypeUtils to guard against the use of older Java versions.
Both `Collection` and `Map` type lookups now fallback to generic free

Spring Boot's annotation processor could result in
`IllegalArgumentException: Incorrect number of type arguments`.

Previously, Maven repositories definition was specified in a profile that
is active by default. It means that as soon as any profile is enabled by
the user, said profile is no longer enabled. This has the nasty
consequences of having copy/paste in several places to make sure our own
profiles still have the proper repositories definition.
This commit creates a single "repositories" profile that is always active
unless a given property is explicitely specified. This allows to remove
the duplication and make things more consistent.
Some Gradle-specific repositories were also hard-coded in two modules
without any profile at all, meaning they were polluting the build of
anybody using it. While the impacted modules are gradle specific, that
repository has been shared in the new "repositories" profile as well.
Closes gh-6031
Previously, JarURLConnection didn't override getPermission(). This
meant that it required all permissions. This was at odds with the
Oracle JVM's concrete sun.net.www.protocol.jar.JarURLConnection which
overrides getPermission to return a FilePermission with the read
action for the path of the underlying jar.
This commit updates our JarURLConnection to align its behaviour with
sun.net.www.protocol.jar.JarURLConnection.
Closes gh-5411
In Maven land, provided and system-scope dependencies are very similar,
the latter being an special kind that allows you to specify the path to
the artifact rather than using the repository to locate it.
Prior to this commit, the repackage goal of the maven plugin was
inconsistent as it would repackage provided-scope dependencies but would
ignore the system-scoped ones.
This commit adds an extra boolean flag, `includeSystemScope` to control
this behaviour. For backward compatibility reasons, its default value is
`false`.
Closes gh-2224
Previously, arguments passed to the script were handled in one way
if a service was being started using start-stop-daemon and in another
way if start-stop-daemon wasn’t available or the application is being
launched in run mode. This meant that quoted arguments were only
handled correctly when the application was being started using
start-stop-daemon.
This commit updates the launch script so that argument handling is
the same across all three different way that the application can be
launched.
Closes gh-5942
Using a separate thread to call the application's main method is
unnecessary – the context class loader of the current thread can be
updated instead – and makes exception and exit code handling more
complicated than it needs to be.
This commit updates the Launcher so that it calls the main method
runner using the current (main) thread. As a result, any exception
that's thrown will be caught by the JVM and result in a non-zero exit
code being returned from the process.
Closes gh-5922
Previously, if the folder which contained the jar was a symlink the
launch script would use the symlinked folder's name when determining

when determining the script's default identity. The behaviour when
APP_NAME has been set is unchanged.

This commit improves the `InfoContributor` infrastructure as follows:
* `InfoEndpoint` no longer breaks its public API and returns a Map as
before
* `Info` is now immutable
* All properties of the build are now displayed. Since we control the

shown
* Build info is now generated in `META-INF/build-info.properties` by
default

Previously, if a void method with a single argument was named "set", the

Closes gh-5826
Previously, the Gradle plugin would include all of the dependencies
from both the compile and runtime configurations in the repackaged
jar. In the unlikely event that the compile and runtime configurations
contained different versions of the same dependency, this would lead
to both versions of the dependency being packaged in the jar file.
The runtime configuration extends the compile configuration so, in
normal circumstances, it will contain a superset of the compile
configuration's dependencies. In the situation described above where
the two configurations contain different versions of the same
dependency the runtime configuration will only contain whichever
version of the two dependencies has "won". By default, this will
be the dependency with the higher version.
This commit updates the Gradle plugin to only include the runtime
configuration's resolved dependencies during repackaging. As explained
above, the runtime configuration extends the compile configuration so
any compile dependencies will still be included, with the added
benefit that duplicate versions of the same dependency will have been
resolved to a single, preferred version.

Previously, a JVM that was forked by spring-boot:run could be orphaned
when the parent process (the Maven build) was terminated in an IDE. Note
that this doesn’t happen when spring-boot:run is invoked from a shell.
This commits add a shutdown hook that registered when RunMojo forks the
JVM. The shutdown hook attempts to kill the forked JVM’s RunProcess
rather than relying on the death of the parent process being sufficient
to also kill the child.

Previously, the CLI would always use the class loader to try to locate
a source file. This was contrary to the SourceOptions javadoc which
states that the class loader is “used to try and load files that are
not found in the local filesystem”. This provide to be problematic on
Windows when a fully-qualified source file was supplied. The driver
letter colon slash (e.g. c:/) at the start of the path is considered
invalid for a class path resource by URLClassPath.Loader resulting in an
IllegalArgumentException being thrown.
A workaround for this URLClassPath behaviour was added in a71c9b5d. It
was removed as part of reworking LaunchedURLClassLoader to use a
conventional delegation model in 87fe0b2a. It was then reinstated in
cc140b2c. This work around is undesirable as it causes
LaunchedURLClassLoader’s behaviour to diverge from URLClassLoader’s
behaviour (this is contrary to the comments in the test added in
a71c9b5d which incorrectly tests the two class loader with different
class paths. If the two class loaders are created with the same class
path then their behaviour is the same).
This commit updates SourceOptions to make its behaviour match its
javadoc so that a search of the class path is only performed if the
filename doesn’t exist on the filesystem. Furthermore, when running on
Windows, if the filename is an absolute path no further searching is
performed as the path cannot reliably be used to search the class path
due to the behaviour of URLClassPath.Loader when given a path that
is an absolute file path on Windows. This ensures that the user is
presented with an error message indicating that the file could not be
found.

Previously, JarURLConnection would fail when created with a URL that

Previously, JarLauncher considered any entry whose name began with
BOOT-INF/classes/ as being a nested entry. This was incorrect as it
meant that subdirectories of BOOT-INF/classes/ would be added to the
classpath rather than just BOOT-INF/classes/ itself.
This commit updates JarLauncher so that only directory entries with a
name equal to BOOT-INF/classes are used.
Closes gh-5610
Previously, if a JarFile was created from a directory nested inside
another jar file, it would look for the manifest in
pathFromRoot/META-INF/MANIFEST.MF. This is incorrect as, unlike a
JarFile created from a jar file, the archives are one and the same
so the manifests should be too.
This commit updates JarFile so that its aware of how it was created
(direct from a file, from a nested directory, from a nested jar). If
it was created from a file or from a nested jar, it uses its manifest.
If it was created from a nested directory, it uses the manifest of the
root archive.
Closes gh-5609
Previously, if loader.path directly specified a jar file that contained
nested archives (.zip or .jar), launching would fail unless those
nested archives were uncompressed. However, if loader.path specified a
directory that contained such a jar file the launch would succeed. This
was because the nested archives within the jar were ignored.
This commit updates PropertiesLauncher so that its behaviour in the
scenarios described above is consistent by not looking for archives
nested with a jar that’s be specified on loader.path. The javadoc for
loader.path has also been updated to make it clear that loader.path
can points to directories or jar files, bringing it into line with
the reference guide.
Closes gh-3701
Following changes to LaunchedURLClassLoader made in 87fe0b2a, it is
no longer necessary for the launcher to load MainMethodRunner via
reflection as both the app class loader that the launcher URL class
loader share the same MainMethodRunner class.
This commit takes advantage of this by updating Launcher to instantiate
MainMethodRunner directly rather than via reflection, removing one
source of possible exceptions in the launcher.
As the MainMethodRunner is now loaded directly and its class is shared
between the two class loaders, there’s no longer a need for it to
implement Runnable. This allows it to throw Exception from its run
method, rather than having to wrap any Exception in a RuntimeException.
Lastly, rather than catching any exception thrown from the launch,
Launcher and its subclasses have been updated to allow this exception
to be thrown from the main method. This allows the Exception to reach
the JVM, to be processed by our registered uncaught exception handler,
and to trigger the JVM’s standard processing for exiting due to a
failure. This removes the need for the Launcher itself to call
System.exit(1) and ensures that the exception is only output to the
console if it hasn’t been registered as a logged exception.
Closes gh-5358
Previously, the default BuildInfo task created by the DSL was called
buildInfo. Due to Gradle's lack of namespacing for tasks, this meant
there was a slight risk that it could clash with another task. It
also didn't following the naming used by Boot's run task which is
named bootRun.
This commit renames the default BuildInfo task to bootBuildInfo to
match bootRun and to hopefully avoid clashes with tasks from other
plugins.
Closes gh-5518
Previously, FindMainClassTask would look for a property named main
on any class named run. This was based on the assumption that the
run task would be a JavaExec task (typically provided by the
application plugin). If the run task was not a JavaExec task (more
accurately, if it did not have a main property) this would result in
a build failure due to trying to read a non-existent property.
This commit updates FindMainClassTask to only use the main property
of the run task if the task is a JavaExec task. This guarantees that
the property will exist on the task, and unlike using any property
named main on a task named run, also guarantee that its value will
refer to a Java class with a main method.
Closes gh-5501
Previously, when defining a package for a class, LaunchedURLClassLoader
would use the manifest from the first location that contained the
required package. If the package was split across multiple locations,
this could lead to the manifest from a jar other than the one that
contains the class being used.
This commit updates LaunchedURLClassLoader so that it will use the
manifest of the jar file that contains the class which triggered the
definition of the package.
Closes gh-5485
LaunchedURLClassLoader preemptively defines the package for any
classes that it attempts to load so that the manifest from a nested
jar is correctly associated with the package. This can lead to a race
where the package is defined on two threads in parallel, resulting
in an IllegalArgumentException being thrown.
This problem was manifesting itself as a NoClassDefFoundError.
If the initialization of a class failed due to the above-described
IllegalArgumentException, subsequent attempts to use that class
would then fail with a NoClassDefFoundError.
This commit updates LaunchedURLClassLoader to catch the
IllegalArgumentException and then double-check that the package has
already been defined. This approach, including thrown an
AssertionError when the second check fails, is modelled on the
approach taken by URLClassLoader.
Closes gh-5464
The commit adds a new BuildInfo task that can be used to generate
a build.properties file, intended for inclusion in the Actuator's
info endpoint.
A default instance of the task can be configure using the plugin's
DSL:
springBoot {
buildInfo()
}
Additional properties can also be configured using the DSL:
springBoot {
buildInfo {
additionalProperties = [
'foo': 'bar'
]
}
}
When configured via the DSL, the Java plugin's classes task is
configured to depend on the build info task. Alternatively, if more
control is required, the task can be declared and configured manually:
task buildInfo(type: org.springframework.boot.gradle.buildinfo.BuildInfo) {
additionalProperties = [
'foo': 'bar'
]
}
classes {
dependsOn buildInfo
}

This commit updates the Maven plugin to generate a
`META-INF/boot/build.properties` file with various build-specific
settings (group, artifact, name, version and build time). Additionally,
the plugin can be configured to write an arbitrary number of additional
properties.
A new `BuildProperties` bean is automatically exposed when such a file is
present. If that bean is present, an `InfoContributor` is automatically
created to expose that information under the `build` key.
As for the git contributor, it is possible to only display the core
settings or everything using the `management.info.build.mode` property.

Previously, the Launcher would call ex.printStackTrace for any
exception that was thrown when launching the application. This was
unnecessary as the stack trace should already have been logged by

failure analysis.

This commit upgrades Animal Sniffer to 1.15 and adds the necessary

APIs.
Note that UsesUnsafeJava has been copied from spring-boot and made

in the build order that would be necessary for
spring-boot-loader-tools to use the annotation from spring-boot.

Previously, JarURLConnection would corrupt a URL that contained a
mixture of encoded and unencoded double-byte characters. URLs that
only contained unencoded double-byte characters were not affected as
they are passed through as-is.

characters with a value that won't fit in a single signed byte (a
value greater than 127). Such characters are now URL encoded and then
written to the output stream as multiple bytes.
Closes gh-5194
When an application is run as an executable archive with nested jars,
the application's own classes need to be able to load classes from
within the nested jars. This means that the application's classes need
to be loaded by the same class loader as is used for the nested jars.
When an application is launched with java -jar the contents of the
jar are on the class path of the app class loader, which is the
parent of the LaunchedURLClassLoader that is used to load classes
from within the nested jars. If the root of the jar includes the
application's classes, they would be loaded by the app class loader
and, therefore, would not be able to load classes from within the
nested jars.
Previously, this problem was resolved by LaunchedURLClassLoader being
created with a copy of all of the app class laoder's URLs and by
using an unconventional delegation model that caused it to skip its
parent (the app class loader) and jump straight to its root class
loader. This ensured that the LaunchedURLClassLoader would load both
the application's own classes and those from within any nested jars.
Unfortunately, this unusual delegation model has proved to be
problematic. We have seen and worked around some problems with Java
Agents (see gh-4911 and gh-863), but there are others (see gh-4868)
that cannot be made to work with the current delegation model.
This commit reworks LaunchedURLClassLoader to use a conventional
delegate model with the app class loader as its parent. With this
change in place, the application's own classes need to be hidden
from the app class loader via some other means. This is now achieved
by packaging application classes in BOOT-INF/classes (and, for
symmetry, nested jars are now packaged in BOOT-INF/lib). Both the
JarLauncher and the PropertiesLauncher (which supports the executable
jar layout) have been updated to look for classes and nested jars in
these new locations.
Closes gh-4897

Previously, the Launcher was creating a new runner thread that would
call the application's main method. An exception thrown by this thread
is handled differently to one thrown by the JVM's main thread leading
to different exit behaviour. Furthermore, the separate thread isn't
actually necessary.
This commit removew the use of a separate runner thread from the
Launcher. This means that the JVM's exit behaviour will be consistent
and also removes the overhead of createing a starting an extra thread.

Refactor `spring-boot-loader` to reduce the amount of memory required
to load fat & exploded jars. Jar files now no longer store a full list
of entry data records, but instead use an array of entry name hashes.
Since ClassLoaders often ask each JAR if they contain a particular
entry (and mostly they do not), the hash array provides a quick way to
deal with misses. Only when a hash does exist is data actually loaded
from the underlying file.
In addition to the JarFile changes, the Archive abstraction has also
been updated to reduce memory consumption.

Commit 5a1ee6eb added support for disabling use of start-stop-daemon

This commit reinstates the placeholder and adds tests to verify that all
of the placeholders in the launch script can be replaced and that they
have the required default values. Furthermore, it also allows the use of
start-stop-daemon to be configured via USE_START_STOP_DAEMON in an
app’s .conf file. This allows the configuration to be changed after the
app has been built.

Previously, if an application’s main method threw an exception,
MainMethodRunner would catch the exception and call System.exit(1).
This meant that the JVM would exit, irrespective of whether or not
any non-daemon threads were running. In contrast, when an application’s
main method was invoked directly (in an IDE, for example) the JVM
would not exit if one or more non-daemon threads were running. This
is standard JVM behaviour that we should be consistent with in the
launcher.
This commit updates MainMethodRunner to wrap any exception thrown by an
application’s main method in a RuntimeException and rethrow it. This
alllows the JVM to handle the exception and use its normal rules for
deciding whether or not it should exit.

PropertiesLauncher creates a ClassLoader that is used by the Launcher
to load an application’s classes. During the creation of this
ClassLoader URLs from its ClassLoader. This resulted resulting in Java
agents that are added to the system class loader via the -javaagent
launch option being available on both the system class loader and the
created class loader. Java agents are intended to always be loaded by
the system class loader. Making them available on another class loader
breaks this model.
This is the same problem that was in ExecutableArchiveLauncher and
that was fixed in ee08667e (see gh-863).
This commit updates PropertiesLauncher so that it skips the URLs of
any Java agents (found by examining the JVM’s input arguments) when
copying URLs over to the new ClassLoader, thereby ensuring that Java
agents are only ever loaded by the system class loader.
Closes gh-4911
Previously, the default launch script would send SIGTERM once and then
wait for up to 60 seconds for the app to have stopped. If the service
was stopped immediately after being started the first SIGTERM would
occasionally be ignored (presumably because the JVM was not yet in a

This commit updates the launch script to resend SIGTERM to the process
if it's still running 30 seconds after the first SIGTERM was sent.

81a4763 introduced a regression when multiple RUN_ARGS or JAVA_OPTS were
configured. Rather than the JVM being launched with multiple arguments
all of the RUN_ARGS or JAVA_OPTS were passed as a single argument. This
caused unexpected behaviour and typically caused the application to fail
to start.
This commit updates the quoting of the arguments the are supplied when
launching the app using start-stop-daemon so that space-separated
entries in RUN_ARGS and JAVA_OPTS remain separate.

Previously, the launch script used which to determine the availability
of start-stop-daemon. which isn’t available by default on all OSs.

start-stop-daemon is available. This improves the portability of the

Previously, the launch script would wait for the pid file to exist
before continuing. This didn’t work 100% of the time as it left a

start.
This commit updates the script to wait for the file to have a size
greater than zero before continuing. This ensures that the pid has
been written to the file before the pid is read from the file and used
to check that the process is running.

There’s a race condition in start-stop-daemon when --make-pidfile and

Some libraries like aspectj are using findResource to see the raw
bytecode of a class. It will even call findResource for every method of
every class of beans that are post processed. This can be significant
performance hit on startup when LaunchedURLClassLoader and there are a
lot of nested jars.

The Maven POM does all the dependency resolutions for the
spring-boot-antlib project. Delegating this task to Ivy, which is
buried deep in the Antrun/Antunit part of the build, makes any kind
of proxy configuration much more complex.
The ivysettings.xml already has the local M2 repository configured,
but because the folder "repository" is missing, the artifacts, already
downloaded by Maven cannot be resolved from this location.
The Spring and Maven Central repositories should be removed from the
ivysettings.xml files in order to force all resolves to be done through
the local M2 repository. The POM of joda-time version 2.8.1 has an
optional dependency to joda-convert 1.2, which lets the Ivy resolve
process fail, because this version of the joda-convert library was
not resolved by any of the Maven POMs. It seems as if Ivy does not
respect the optional scope, defined in the joda-time POM.
Pass proxy settings to the forked process to make the Gradle distribution download work
Create a gradle.properties file for each Gradle integration test and writes the forking
process' proxy settings as systemProp.http(s).Host/Port to the properties file.
This configures the external process with the right proxy settings to let it download
the Gradle distribution via the HTTP proxy server.
Added a hint for Windows users to get the core.autocrlf setting right
When the core.autocrlf setting under Windows is set to false for example
All files are not converted regarding their EOL characters to the
Windows format with CRLF at a line's end. There is a checkstyle
validation that checks that all files have the system's line endings
and in some test-cases the value from the system property "line.ending"
is used to check test output. So without the conversion, those checks
are going to fail, resulting in build errors.

Previously, the meta-data annotation processor was taking the first
setter that match the property name it has to handle. Contrary to
getters that are enforced by a return type (no argument), multiple
setter candidates may exist.
If a property's type got narrowed over time, the original setter may
have been marked as Deprecated. As the annotation processor takes the
first setter that matches based on the name only, it may pick up the
deprecated one and therefore mark the property as being (wrongly)
deprecatede in the meta-data.
It turns out that checking for the actual type of the setter parameter
brought a side effect: some primitive properties may use the primitive
or the Wrapper counter part. This commit not only look at the proper
setter based on the type but also fallback on the wrapper (or) primitive
if necessary.
Closes gh-4338
By default, start-stop-daemon will chdir to the root directory before
starting the process. This prevents an application.properties file that

Update the "INIT INFO section" of `launch.script` to include

Flip the default value of `addResources` for both the Maven and Gradle

As devetools is our mainstram solution for such feature, the documantion
has been updated to reflect that.

The init script spec [1] describes a number of requirements with which
our launch.script did not comply. This commit makes the following
corrections:
- Add support for force-reload which should be implemented by all
init scripts
- Don't fail restart if the service is already stopped or not running
- Consider stop to be successful if the service is already stopped
- Exit with 1 if stop fails (indicating a generic or unspecified error)
rather than 3 (unimplemented feature)
- Report a status of 1 if app is not running but the pid file exists
- Report a status of 3 if the app is not running (no pid file)

Previously, the launch script would always use a file named

This commit adds a dedicated property to specify the active profiles to

Previously, JarFileArchive would always unpack any entries marked for
unpacking to ${java.io.tmpdir}/spring-boot-libs. This could cause
problems if multiple Spring Boot applications were running on the same
host:
- If the apps are run as different users the first application would
create the spring-boot-libs directory and the second and subsequent
applications may not have write permissions to that directory
- Multiple apps may overwrite each others unpacked libs. At best this
will mean one copy of a jar is overwritten with another identical
copy. At worst the jars may have different contents so that some of
the contents of the original jar disappear unexpectedly.
This commit updates JarFileArchive to use an application-specific
location when unpacking libs. A directory beneath ${java.io.tmpdir} is
still used but it's now named <jar-file-name>-spring-boot-libs-<uuid>.
A loop, limited to 1000 attempts, is used to avoid problems caused by
the uuid clashing.

Previously, manual meta-data were added to the existing set of entries
which could lead to duplicates if a manual entry is meant to complement
a property that is detected via the processor.
We now match the name and type of the item against the auto-detected
entries. If no match is found, we add the extra entry as we did before.
If a match is found we override the description, default value and
deprecation information.
Closes gh-3562
The annotation processor detects `@ConfigurationProperties` bean or
method definition and merges manual meta-data. The former step will fail
with a NPE if the annotation is not present on the classpath. This could
happen if the annotation processor is added to a module that is not
actually using Spring Boot.
We now have a defensive check that skips that steps but still attempts to
merge manual meta-data if present.
Closes gh-3720
When nested jars are being used, hasMoreElements requires opening a
connection for an entry in every nested jar. If that entry doesn't
exist, a FileNotFoundException is thrown to indicate that a particular
jar doesn't contain the requested entry. This exception is used to
indicate the lack of an entry and is then swallowed, i.e. its stack
trace is of no importance. This means that the performance of
hasMoreElements can be improved by switching on fast exceptions while
it's being called. When fast exceptions are switched on a general
purpose pre-initialized FileNotFoundException is thrown rather than
creating a new FileNotFoundException instance each time.
In certain situations, the use of fast exceptions as described above
can improve performance fairly significantly. The JRE's default SAAJ
implementation uses META-INF/services-based discovery for _every_
request that's handled by Spring Web Services. Each discovery attempt
results in hasMoreElements being called making its performance
critical to throughput.

DevTools look for a main thread named "main". The maven plugin is

8673250 updated the plugin so that the application plugin is no longer
applied by default. This exposed three problems:
1. bootRepackage may run before findMainClass has run, leaving it with
an unknown main class.
2. findMainClass may run before the classes have been built, making it
unable to find the main class by examining the class files
3. The project's mainClassName property was still being used as a
convention for the bootRun task's main property. If the application
plugin has not be applied, then this property does not exist.
The first problem has been addressed by configuring bootRepackage to
depend on findMainClass.
The second problem has been addressed by configuring the main source
set's output as an input of findMainClass, and configuring findMainClass
to depend on the tasks that build the output.
The third problem has been addressed by only using the mainClassName
property if it exists and its value is not null. We then fallback to
using the mainClassName property on the project's extra properties in
the same way.
See gh-2679
Previously, the Spring Boot Gradle plugin would always apply the
application plugin to a project. It then piggy-backed on the application
plugin’s mainClassName and applicationDefaultJvmArgs properties for the
configuration of the bootRun task.
This commit updates the Spring Boot Gradle plugin so that it no longer
applies the application plugin. If the user applies the application
plugin then its configuration will be used, but it’s a no longer
requirement.
Users who do not need the application plugin, but who were using the
mainClassName or applicationDefaultJvmArgs properties will need to
change their builds as a result of this change as those properties will
no longer exist. As before, the mainClassName can be configured on the
springBoot extension:
springBoot {
mainClassName 'com.example.YourApplication'
}
The applicationDefaultJvmArgs property can be used, but it must now be
declared with the project's ext block. For example:
ext {
applicationDefaultJvmArgs = [ '-Dcom.example.property=true' ]
}

Add a new @DeprecatedConfigurationProperties annotation which can be
used by the `ConfigurationMetadataAnnotationProcessor` to generating
meta-data deprecated blocks.
Fixes gh-3543
Previously, an item could only have a 'deprecated' boolean flag to
indicate that the property is deprecated. It is desirable to provide an
additional description for the deprecation as well as the name of the
property to use instead.
The `deprecated` boolean flag is now supported. Instead, a `deprecated`
object can be specified with two optional attributes: `reason` to provide
an explanation for the deprecation and `replacement` to refer to the
property that should be used instead. If none of them is present, an
empty deprecation object should be set.
For backward compatibility, the `deprecated` field is still set.
Deprecation information can only set via manual meta-data.
Closes gh-3449
If a field is initialized via a factory method taking a single argument,
we can relatively safely consider that said argument is a good
representation of its default value. This is typically the case for
Charset or MimeType instances.
We now make sure to detect such use case (i.e. method argument with a
single argument).

I think this is safe, judging by the integration tests, but I'm not
putting it in 1.2.x until we've had some feedback on it. The
integration tests actually had a bug that was masking this problem
because they were merging Properties from the whole classpath instead
of picking the first available resource (which is generally what
we do in Spring Boot applications for application.properties for
instance).

Liquibase has a `changeLog` property that is definitely used as a
`Resource` but cannot be defined as such as the original String value

keeps all its auto-discovered capabilities.

When writing a jar, once an entry has been written it will never be
overwritten, i.e. the first write of a given entry will win. Previously,
when repackaging a jar, the existing contents were written followed by
any libraries. This caused a problem when repackaged a WAR file and
a library needed to be unpacked as the existing entry in WEB-INF/lib
would prevent the library with the UNPACK comment from being written.
This was addressed in f761916b by inverting the order so libraries
would take precedence over entries in the source jar.
It’s now become apparent that this change in the order causes a problem
for users who are obfuscating their code. The obfuscated code exists in
the source jar but is also provided to the repackager in its original
form as a library. When libraries take precedence, this means that the
code in its original form ends up in the repackaged war and the
obfuscation is lost.
This commit updates the repackager to write libraries that require
unpacking first. This allows the UNPACK comment to be written even if
there’s also a source entry for the library. Next, source entries are
written. This allows obfuscated source entries to take precedence over
any unobfuscated library equivalents. Lastly, standard libraries that
do not require unpacking are written into the repackaged archive.
Closes gh-3444
Previously, if the repackaged file was different from the main artifact
of the build, the maven plugin wrongly considered that it should attach
the file with a classifier.
The outputDirectory is honored properly now, regardless of the fact a
classifier is defined or not.

Improve the "hints" section of the metadata so that each hint can provide
the reference to a value provider.
A value provider defines how a tool can discover the potential values of
a property based on the context. The provider is identifed by a name and
may have an arbitrary number of parameters.
Closes gh-3303
Create a new section in the meta-data called "hints" where users can
provide hints about a given property. The most basic use case for now
is to provide a list of values that a property can have. Each value may
have a description.
This sample JSON provides a basic example for a property called `foo.mode`
that exposes 3 values: "auto", "basic" and "advanced".
```
"hints": [
{
"id": "foo.mode",
"values": [
{
"value": "auto",
"description": "Some smart description."
},
{
"name": "basic"
},
{
"name": "advanced"
}
]
}
]
```
This information can be read by tools (such as IDE) and offer an
auto-completion with the list of values.

`ArtifactHandler`.

SpringApplicationLifecycle provides basic lifecycle operations on the
current Spring Boot application (that is checking if the application has
fully started and gracefully terminate the app). It can be registered as
an MBean of the platform MBean server if a specific property is set.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.
Such change permits the maven plugin to integrate a classical integration
test scenario where the "start" goal is invoked during the
pre-integration phase and the "stop" goal during the post-integration
phase.

Previously, the CLI’s dependency management used proprietary Properties
file-based metadata to configure its dependency management. Since

dependency management. By default it uses the spring-boot-dependencies
bom. This configuration can be augmented and overridden using the new

This reverts commit b1c0a7cda4.
The plugin publishing process has moved to a new plugin-based approach
that brings with it some significant limitations:
- There's no staging to allow the promotion of good release builds
- There's no easy way to upload an existing artifact
- There's no control over the published pom.
The risk brought by these limitations, particularly the first, are
too great so we will no be publishing the Boot plugin to the Portal
until they're resolved.
Changing the plugin's ID was a breaking change that would require
users to do some work when they upgrade to Boot 1.3. The ID of the
plugin was changed purely so that it met the Portal's requirements.
Given that the plugin will not be published to the Portal for the
foreseaable future there's no need for us to inflict a breaking change
on people when there will be no benefit.

SpringApplicationLifecycle provides lifecycle operations on the current

also be customized via a property in case more than one Spring Boot

The format is rather unusual.
The time is 16 bits: 5 bits for the hour, 6 bits for the minutes, and 5
bits for the seconds. 5 bits only allows 32 values (0-31) so the number
must be doubled, meaning that the time is only accurate to the nearest
two seconds. Also, the JDK rounds this down by subtracting one. The
doubling and rounding is performed by shifting one place to the left
and masking off the right-most bit respectively.
The date is 16 bits: 7 bits for the year, 4 bits for the month, and 5
bits for the day. The year is from 1980, i.e. the earliest date that
can be represented is 1980-01-01.

Previously repackaging of an archive was performed in three steps:
1. Write the manifest
2. Write entries from the source archive into the destination
3. Write any libraries into the destination if they’re not already there
This worked fine for jar files, but not for war files. In the war file
case the libraries are already in the source archive’s WEB-INF/lib
directory so they’re copied into the destination in step 2. This means
that step 3 largely becomes a no-op and, crucially, the UNPACK comment
is not applied to any libraries that require it.
This commit reorders steps 2 and 3 so that the libraries are copied into
the destination first (allowing the UNPACK comment to be written, if
required) and then any entries in the source are written into the
destination if they’re not already there.
