It seems like the gfm root package should specify "targetType": "none" instead of just removing all source/import paths. But since this has obviously worked before, I'll add a check/workaround for this and output a warning to use "targetType" instead.

Sorry for not having done that, there is a problem indeed with targetType. It's just that I didn't know which JSON properties get inherited or not.
