Update the `Launcher` class to allow a packaged jar to be launched in
a different mode. The launcher now checks for a `jarmode` property and
attempts to find a `JarMode` implementation using the standard
`spring.factories` mechanism.
Closes gh-19848
This commit removes references of cache infra following the move to
Micrometer. We no longer ships an infinispan specific binder so the
dependency has been removed as well.
Closes gh-19838
Previously, the generated resources were added as an output to the
main source set. This worked on the command line, but resulted in
the META-INF folder that contains the loader jar not being on the
classpath of downstream projects in Eclipse.
This commit changes loader-tools to add the generated resources
as a srcDir to the main source set. This results in it appearing on
the classpath of other projects in Eclipse that depend on loader-tools
such as the Gradle plugin, thereby allowing its tests to be run in
the IDE as well as on the command line.
Fixes gh-19841
Previously, we were adding dependencies to Ant's ClassLoader within
Gradle. It is suspected that this was causing sporadic loader
contraint violations as types that Gradle itself uses (from Commons
Compress) were then available from two different ClassLoaders.
This commit reworks the Ant smoke test to use JavaExec and Ant's
launcher to run the build. This allows us to make the necessary
dependencies available to Ant in an isolated manner. The javac
invocation within Ant is now forked to allow it to find the tools jar
even when the build itself is running on a JRE.
Closes gh-19839
Pull functionality from `Repackager` into a new `Packager` base class
and develop a variant for Docker image creation. The new `ImagePackager`
class provides a general purpose way to construct jar entries without
being tied to an actual file. This will allow us to link it to a
buildpack and provide application content directly.
Closes gh-19834
Add a Java implementation of the buildpacks.io specification allowing
projects to be packaged into OCI containers. The `builder` class
provides a Java equivalent of `pack build` command and is based on
the `pack` CLI Go code published at https://github.com/buildpacks/pack.
Closes gh-19828
