Previously, the classpath of bootJar, bootWar, and bootRun was
configured directly as a FileCollection derived from the main source
set's runtime classpath. This direct configuration meant that
subsequent changes to the main source set's runtime classpath may not
have been picked up.
This commit changes the configuration of the classpath to use a
Callable. This indirection allows subsequent changes to the main
source set's runtime classpath to be picked up as long as they
occur before Gradle calls the callable.
Closes gh-29672
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 `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
Adding a label to the ephemeral builder image cloned from the base
builder image eliminates contention between builds that are run
concurrently. Without this label, concurrent builds could result in
a race condition in the Docker daemon if the ephemeral builder image
shared by builds was deleted by both builds at exactly the same time.
Fixes gh-27888
