Previously, unlike the application plugin's run task, our bootRun task
ignored the project's Java toolchain. This meant that the application
was run on a JVM with the same Java version as the one being used by
Gradle itself. This could result in a failure if the application
required a more modern JVM.
This commit updates the plugin to configure the bootRun task's
JavaLauncher convention to be one derived from the project's Java
toolchain. Toolchain support was introduced in Gradle 6.7 so this is
only done when using Gradle 6.7 and later.
Fixes gh-24517
Previously, bootRun assumed that the Java version of the JVM that would
run the application would be the same as the Java version of the JVM
that is running the build. This assumption does not hold true when
Gradle's toolchain support is used to configure tasks that fork a new
JVM to use a version other than that being used by Gradle itself.
This commit updates the BootRun task to query the JavaLauncher property
when determining the version of Java on which the application will be
run. Toolchain support and the JavaLauncher property are new in Gradle
6.7. To support earlier versions of Gradle, NoSuchMethodError is caught
we continue as if no JavaLauncher has been configured and use the local
JVM's Java version.

Prior to this commit, running the bootBuildImage Gradle task on a
project configured for war packaging would result in a jar file being
built and used in the image instead of the war file. With this commit
an error will be thrown from the plugin in this case.
Fixes gh-24521
This commit sets the pull policy to `IF_NOT_PRESENT` where possible
in integration tests for the Maven and Gradle plugins to reduce
the number of times the default Paketo builder and run images are
pulled from Docker Hub.

When a Configuration is copied, any before and after resolve actions
that are registered with its ResolvableDependencies are also copied
over. This means that, when a copied configuration is resolved the
resolution actions may be called on a ResolvableDependencies instances
that isn't the one to which they were added.
Previously, the above-described Gradle behaviour would result in
BootJar accessed the ResolvedConfiguration of a Configuration that may
not have yet been resolved. At best this would trigger Configuration
resolution and at worst it would fail. A failure could occur if the
configuration had been copied so that it could be made resolvable.
The afterResolve action would then try to access the
ResolvedConfiguration of the original Configuration. This would trigger
a resolution attempt that fails due to the original configuration being
marked as unresolvable.
This commit updates the afterResolve action in BootJar to check that
the ResolvableDependencies with which it is called matches the
ResolvableDependencies with which it was original registered. Only
when the two match, and therefore the configuration has actually been
resolved, does processing proceed.
Fixes gh-24072
Previously, when building a layered jar with Gradle, project
dependencies were treated the same as any other dependency, being
included in the dependencies or snapshot dependencies layer based
on their version.
This commit updates the default layering when using Gradle to include
project dependencies in the application layer by default. The DSL has
also been updated to allow their layer to be customized using new
includeProjectDependencies() and excludeProjectDependencies() methods
rather than relying on including and excluding them via a
group:artifact:version pattern.
