how to handle this sort of plugin...

Don't know how one might handle this...

We (like quite a few others I suppose) have tools that generate Java course.

We also generate some files with multiple other files as inputs.

So what is a good way to handle, say, a file type XYZ that when compiled (by our own code) inside IDEA then creates/updates another Java file whose symbols must be visible and must compile in the same compilation pass?
