Gradle 9.x identifies the custom LicensesCleanUpTask as a hard failure due to implicit dependency conflicts with generation tasks. Standard Gradle 'clean' (Delete) already handles the build directory idiomatically. - Removed LicensesCleanUpTask.groovy and its corresponding test. - Refactored EndToEndTest.kt to use a createRunner() helper with forwardOutput() and strict configuration cache validation. - Optimized parallel test execution by isolating TestKit directories per test class. - Updated build.gradle.kts with optimized heap settings and live test event logging. - Added .kotlin/ to .gitignore to prevent tracking of local metadata. Closes #356, #300, #299
…e support This update modernizes the build environment and ensures task outputs are correctly cached and relocatable. - Upgraded Gradle wrapper to 9.4.0 in oss-licenses-plugin. - Added @CacheableTask, @nested, and @PathSensitive annotations to core tasks. - Implemented an automated relocatability test in EndToEndTest.kt. - Verified 100% parallel throughput with isolated TestKit directories. Closes #356
…racks Updated the E2E test matrix to cover the latest AGP tracks: - Stable: AGP 9.0.1 - RC: AGP 9.1.0-rc01 - Alpha: AGP 9.2.0-alpha02 Also updated Kotlin version expectation logic to correctly handle AGP 9.1 and 9.2.
Increased Xmx to 2048m and MaxMetaspaceSize to 1024m to prevent daemon resets during intensive parallel E2E tests.
Refactored testRelocatability to use the setupProject helper, ensuring project structure consistency across cloned directories.
Modified populate() in testRelocatability() to explicitly skip build/ and .gradle/ directories during copying. This guarantees that the relocated projects start from a pristine state, correctly verifying cache relocation instead of hitting UP-TO-DATE due to accidental output duplication.

Resolved conflicts in EndToEndTest.kt by preserving modernization and relocatability logic while integrating the clean task removal from main.
