Update `JarWriter` so that entry times are set with the default TimeZone
offset removed. The Javadoc for `ZipEntry.setTime` states:
The file entry is "encoded in standard `MS-DOS date and time format`.
The default TimeZone is used to convert the epoch time to the MS-DOS
data and time.
Removing the offset from our UTC time before calling `entry.setTime()`
ensures that we get consistent bytes in the zip file when the output
stream reapplies the offset during write.

Update `launch.script` so that the `run_user` variable is only set when
the user actually exists. Prior to this commit, if the jar file was
owned by a non-existing user the startup script could fail.
Fixes gh-29370
Previously, when writing a repackaged jar, an attempt to write all of
an entry's parent directories would always be made, irrespective of
whether or not the entry itself had already been written. This was
inefficient as, due to the way that the jar is written, once an entry
itself has been written, we know that all of its parent directories
will also have been written.
This commit updates the jar writer so that no attempt is made to
write parent directory entries if the entry itself has already been
written.
Fixes gh-29175
Update the Maven and Gradle packaging for war files so that a
`classpath.idx` file is written into the archive that provides the
original order of the classpath, as was previously done for jar files.
The `WarLauncher` class will use this file when running as an exploded
archive to ensure that the classpath order is the same as when running
from the far war.
Fixes gh-19875
Update Maven and Gradle plugins to allow build info properties to be
excluded.
Prior to this commit, the `BuildPropertiesWriter` would fail with an
NPE if the group, artifact, name or version properties were `null`.
This was specifically problematic with the Gradle plugin, since its
DSL allows `null` properties which would either be passed to the writer
or, in the case of `artifact`, converted into a string value of
"unspecified".

When a Maven build is configured to ensure reproducibility, any
libraries added to `BOOT-INF/lib` in a jar archive or to `WEB-INF/lib`
in a war archive by the Spring Boot plugin repackaging should be
sorted by name to ensure a stable and predictable order.
Fixes gh-27436
An upgrade to Apache Commons Compress allows the build plugins to write
the launch script to the fat jar as a proper preamble, making the file
compatible with more jar and zip tooling.
Fixes gh-22336
Update `RepackageMojo` and supporting classes so that `exclusions`
on the repackage goal apply to both the contributed libraries and any
existing jar entries already contained in the original war.
Prior to this commit, exclusions would apply to contributed jars (for
example, those in `WEB-INF/lib-provided`) but not jars that were
packaged directly into `WEB-INF/lib` by the war plugin
Fixes gh-15808
