The "generate" goal of the uimaFIT maven plugin should include type system imports in the generated descriptors. This would make those descriptors directly usable in descriptor-based workflows such as CPE or UIMA-AS.
In our case, we point to the TS descriptor files directly in types.txt, thus not relying on any "magic" TS discovery. This could translate directly to a corresponding import by name in the XML descriptor. More sophisticated setups might of course be more difficult to handle.
