Thanks Curtis, that method (#getArtifactsInTopologicalOrder) is not far from my own code (they both use DependecyGraphBuilder to resolve the deps). But the first parameter of that method is the MavenProject for which you want the resolved dependencies, and that is the piece I am missing. I have an Artifact and if I could convert it into a MavenProject then that approach should work.
So if I can't resolve the dependencies for an Artifact directly, then resolving an Artifact into it's MavenProject would be enough to get me moving forward.
