Previously, the targetJavaVersion property of bootBuildImage was set
using the project's target compatibility directly. This meant that
property's value would reflect the configured target compatibility at
the time of the task's creation and any subsequent changes to the
target compatibility would be missed.
This commit updates the registration of the bootBuildImage task to set
the value of the targetJavaVersion property using a provider. This
indirection means that the project's target compatibility isn't read
until the value of the targetJavaVersion is read, allowing any changes
to the target compatibility to be picked up even if they're made after
the bootBuildImage task has been created.

This commit modifies the integration tests for the Maven and Gradle
image building goal and task to use a custom builder as a test harness
to verify that the plugins invoke the builder as expected.
Fixes gh-25838
Previously, when building a layered jar, the Gradle plugin only
considered a configuration's direct dependencies when identifying
project dependencies. This resulted in transitive project dependencies
being missed when deciding which dependencies belong in the
application layer.
This commit updates ResolvedDependencies to consider all projects
from the root project when collecting the IDs of local projects. This
ensures that any project dependency, no matter where it appears in the
dependency graph, is successfully identified.
Fixes gh-25163
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.
Fixes gh-24512
