Replace RepositorySystem usages with Aether Resolver

[Copilot]

org.apache.maven.repository.RepositorySystem is deprecated and slated for removal in Maven 4.x. This PR migrates all usages to the modern Aether Resolver API (org.eclipse.aether.RepositorySystem), following the pattern established in the maven-compiler-plugin migration.

Migration Pattern

Before:

Artifact artifact = repositorySystem.createArtifact(groupId, artifactId, version, null, packaging);
ArtifactResolutionRequest request = new ArtifactResolutionRequest();
request.setArtifact(artifact);
request.setLocalRepository(session.getLocalRepository());
request.setRemoteRepositories(project.getRemoteArtifactRepositories());
ArtifactResolutionResult result = repositorySystem.resolve(request);

After:

org.eclipse.aether.artifact.Artifact aetherArtifact = new DefaultArtifact(groupId, artifactId, null, extension, version);
ArtifactRequest request = new ArtifactRequest(aetherArtifact, project.getRemoteProjectRepositories(), null);
ArtifactResult result = repositorySystem.resolveArtifact(session.getRepositorySession(), request);

Changes

• MavenDependenciesResolverConfigurer — Migrated to CollectRequest/DependencyRequest/ArtifactRequest APIs
• MavenDependencyInjector — Replaced repositorySystem.createArtifactRepository() with direct MavenArtifactRepository instantiation; removed RepositorySystem and Settings parameters
• P2DependencyResolver — Removed unused RepositorySystem field
• DefaultStandaloneDirectorRuntimeFactory — Removed unused RepositorySystem field
• AbstractEclipseTestMojo — Migrated framework extension resolution to Aether API
• TychoIntegrationTestMojo — Migrated dependency resolution with scope filtering via DependencyFilterUtils
• DocletArtifactsResolver — Migrated to Aether API
• MavenDependenciesResolverTest — Updated test setup to use LegacyLocalRepositoryManager.overlay() for proper session configuration
• P2ArtifactMappingToMavenRepoTest — Replaced RepositorySystem.DEFAULT_REMOTE_REPO_URL constant with literal to remove deprecated import

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• testng.org
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/tools/linux64/java/bin/java /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/xml/tools/xml-extractor.jar --fileList=/home/REDACTED/work/tycho/.codeql-scratch/dbs/java/working/files-to-index10798835212826357474.list --sourceArchiveDir=/home/REDACTED/work/tycho/.codeql-scratch/dbs/java/src --outputDir=/home/REDACTED/work/tycho/.codeql-scratch/dbs/java/trap/java (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>Replace RepositorySystem usages with Aether Resolver</issue_title>
<issue_description>org.apache.maven.repository.RepositorySystem shoudl/could be replaced with Aether Resolver like shown here

https://github.com/apache/maven-compiler-plugin/pull/151/files

For example in the MavenURLHandler.</issue_description>

<agent_instructions>Check where we already use the old org.apache.maven.repository.RepositorySystem and suggest upgrade to using the new Aether API. As we have done this already on some places there should even be examples for such migration in the source code of this repository.</agent_instructions>
