Does anyone know if Gradle Wuff plugin will allow both p2 and Maven (or other) dependencies?

I have a note pending to the author, but does anyone know if the Gradle Wuff plugin, which is used for building Eclipse plugins, will allow getting dependencies from both p2 and Maven (or other) repositories? The Maven Tycho plugin only allows getting dependencies from p2 repos. The codebase I’m working on needs some other third-party jars besides Eclipse dependencies, and the original authors punted and just dumped the other jars into a “lib” folder, which I don’t want to check into SCM.
