How to programmatically list all transitive dependencies, including overridden ones in Maven using DependencyGraphBuilder?

Question

This is similar to other questions (like this), but I want to be able to do this with the latest API's. The maven-dependency-plugin:tree verbose option has been deprecated and does nothing in the latest (2.5.1) code, so there is no good example of how to do it.

I believe Aether utility class from jcabi-aether can help you to get a list of all dependencies of any Maven artifact, for example:

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

If you're outside of Maven plugin:

File repo = new File("/tmp/local-repository");
MavenProject project = new MavenProject();
project.setRemoteProjectRepositories(
  Arrays.asList(
    new RemoteRepository(
      "maven-central",
      "default",
      "http://repo1.maven.org/maven2/"
    )
  )
);
Collection<Artifact> deps = new Aether(project, repo).resolve(
  new DefaultArtifact("junit", "junit-dep", "", "jar", "4.10"),
  "runtime"
);

The only dependency you need is:

<dependency>
  <groupId>com.jcabi</groupId>
  <artifactId>jcabi-aether</artifactId>
  <version>0.7.5</version>
</dependency>
