Making and Submitting Changes
--------------

We accept Pull Requests via GitHub. The [developer mailing list][dev-ml-list] is the
main channel of communication for contributors.  
There are some guidelines which will make applying PRs easier for us:
+ Create a topic branch from where you want to base your work (this is usually the master branch).

        Node root = session.collectDependencies(artifact);
        assertNotNull(root);

        DependencyResolverResult result =
                session.getService(DependencyResolver.class).resolve(session, project, PathScope.MAIN_RUNTIME);
        assertNotNull(result);
        List<Dependency> deps = new ArrayList<>(result.getDependencies().keySet());
        List<Dependency> deps2 = result.getNodes().stream()
                .map(Node::getDependency)
