- [ ] Provide unit tests (under `<subproject>/src/test`) to verify logic.
- [ ] Update User Guide, DSL Reference, and Javadoc for public-facing changes.
- [ ] Ensure that tests pass sanity check: `./gradlew sanityCheck`.

### Reviewing cheatsheet

Before merging the PR, comments starting with 
- ❌ ❓**must** be fixed

import junit.framework.TestCase;
import org.junit.Test;

/**
 * Automatically runs sanity checks against top level classes in the same package of the test that
 * extends {@code AbstractPackageSanityTests}. Currently sanity checks include {@link

 *
 * <pre>

        ArtifactRepository rr2 = repositorySystem.createDefaultRemoteRepository();
        a2.setDependencyFilter(new ExcludesArtifactFilter(Arrays.asList("foo")));

        // sanity checks

### Fixing sanity check failures after public API changes

If your PR includes any changes to the Gradle Public API, it will cause the binary compatibility check to fail.
The binary compatibility check runs as a part of the broader sanity check.
The latter runs on every PR and is a prerequisite for merging.
