Using the "Java" library type, using "Attach Classes" to include the top directory of the module hierarchy, does not work.
How do I do this? (Or is it possible at all?)
Adding the library directory as a source root only works if the library has source (.py) files. If it's all .pyc it does not seem to work. In any case these are libraries and not part of the project source under development, so I would really prefer to have them as "Project Libraries".
