I lloked at the sources: it seems you're including non-existent source directory files. Please open a Jira issue [1] with a sample project as attachement, and I'll fix the plugin to give a better error message on such case.
Note in your pom.xml that specifying a version for archetype plugin and extension is a good practice, or you'll get a non-reproducible build.
