When testing with Gradle 7.6, junit-platform-launcher won't be
on the test runtime classpath unless it's declared as a dependency.
When testing with Gradle 8.x the dependency is added implicitly but
starting with Gradle 8.3 relying on this will result in a warning.
When junit-platform-launcher is absent, a failure occurs when testing
with Gradle as the class loader structure is such that JUnit tries
to load any test execution listeners, finds the listener declared in
spring-boot-actuator-autoconfigure but cannot then load the
implemented TestExecutionListener interface.
This problem is addressed by augmenting the component metadata for
spring-boot-starter-test to add a dependency on
junit-platform-launcher. This addresses the problem with
spring-boot-actuator-autoconfigure while also addressing a warning
with Gradle 8.3+.

When spring-boot-gradle-plugin is using GradleRunner, it needs to be
configured with a custom plugin classpath to account for the fact
that our Gradle plugin is on the classpath of the system classloader
but some of the other plugins would only be available on a
Gradle-created classloader. This imbalance cause class loading
problems as code in spring-boot-gradle-plugin can't see types at
runtime that are only available on the Gradle-created classloader.
To overcome this, we need to configure the GradleRunner with a custom
plugin classpath that contains both spring-boot-gradle-plugin and all
of the other plugins that are used in its various integration tests.
Previously, this was done in GradleBuild that's used by both
spring-boot-gradle-plugin and spring-boot-image-tests. This caused
a problem as spring-boot-image-tests does not have the
above-described problem and trying to correct it did not work leaving
tests that use spring-boot-gradle-plugin unable to see other plugins
such that the native image plugin.
This commit reworks the customization of the plugin classpath so that
it's only done in spring-boot-gradle-plugin's integration tests.

An `imagePlatform` option for the Maven and Gradle image-building
goal/task can be used to specify the os/architecture of any
builder, run, and buildpack images that are pulled during image
building.
Closes gh-40944
The use of method references requires the referenced method to be
present even if it isn't called. This made it impossible for Gradle
to remove the deprecated methods as it would break our plugin.
By switching the lambdas, the methods only have to be present when
they're called which will only happen with Gradle 8.2 and earlier.
Closes gh-41599
A `trustBuilder` configuration option has been added to the Maven and
Gradle CNB integration image building goal and task. A known set of
builders published by Paketo, Heroku, and Google are trusted by default,
all other builders are untrusted by default.
Closes gh-41352
The model incorrectly marks the Gradle API and all of its
dependencies as test dependencies, making them unavailable in Eclipse
to code in src/main/java. We work around this by modifying the
classpath container to remove the test attribute from the
dependencies that should be available to main code.
