How to get access to Maven's dependency hierarchy within a plugin

Question

In my plugin I need to process the dependency hierarchy and get information (groupId, artifactId, version etc) about each dependency and if it was excluded. What is the best

Answer 1

Try to use Aether utility class from jcabi-aether to get a list of all dependencies of any artifact:

File repo = this.session.getLocalRepository().getBasedir();
Collection deps = new Aether(this.getProject(), repo).resolve(
  new DefaultArtifact("junit", "junit-dep", "", "jar", "4.10"),
  JavaScopes.RUNTIME
);
