I got this to work. Incase anyone else needs this...
I was looking at the wrong property on mavenProject. Plexus does not
populate dependencyArtifacts with the dependencies till the compile phase.
However, the property mavenProject.dependencies is populated in the validate
phase. It is populated even if some of the dependencies are not resolved.
But an even better way to get at the dependencies is:
Set<Artifact> dependentArtifactSet =
mavenProject.createArtifacts(artifactFactory, null, null);
