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
This commit adds configuration to the Maven and Gradle plugins to
allow specifying the names of build and launch cache volumes provided
to the CNB builder.

Update `JarURLConnection` to use a single shared wrapper per
jar file rather than creating a new one each time. This update
should help to reduce GC pressure.
Fixes gh-28042
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".
