Update `JarFileEntries` so that the interface is obtained rather than
the concrete implementation. This allows `JarEntry` values to be used
without causing a ClassCastException.
Closes gh-19041
Update the performance improvements to push certificate loading
and storage into the `JarFileEntries` class. This allows us to
keep certificates without needing to cache all entry data. We
now also keep certificates and code signers in a dedicated class
which is set whenever the full jar stream as been read, even if
the contained values are `null`. The logic that assumes META-INF
entries are not signed has been removed in favor of delegating to
the streamed entry results.
See gh-19041
Update Spring Boot nested JarFile support to improve the performance of
signed jars. Prior to this commit, `certificates` and `codeSigners`
were read by streaming the entire jar whenever the existing values
were `null`. Unfortunately, the contract for `getCertificates` and
get `getCodeSigners` states that `null` is a valid return value. This
meant that full jar streaming would occur whenever either method was
called on an entry that had no result. The problem was further
exacerbated by the fact that entries might not be cached.

The generated snippets were not declared as an output to the
`spring-boot-actuator-autoconfigure` test goal so when the test was
pulled from the cache, it did not contain the `generated-snippets`
directory. This directory is required as an input to the Asciidoctor
plugin.
See gh-22555
This adds build caching and build scans.
The changes required disabling scans when using the maven invoker
plugin in order to not cause duplicate build scans when invoking other
maven builds. There is also an empty `.mvn` folder in the
spring-boot-starters project to prevent duplicate build scans as well
since there is no way to pass properties to the maven-javadoc-plugin.
The checkstyle plugin was causing a cache miss with the
`propertyExpansion` because it contains an absolute path. The absolute
path is now ignored and instead the files are added as inputs to the
checkstyle plugin. This only enables the local build cache. The remote
cache is not yet enabled.
On my local machine:
./mvnw clean install build times go from about 30 minutes to about 10 minutes.
./mvnw clean install -Pfull build times go from about 60 minutes to about 13 minutes.
