Hi @m.frank,
If you’re still stuck trying to find the source of the banned import, you can follow the steps I posted here to debug the build process and see exactly where the OSGi package reference is being picked up.
And if it’s not found at build time (meaning the banned package is not listed in your META-INF/MANIFEST.MF) and the error only occurs at runtime when loading your plugin, then you need to double-check that you don’t have any <component-import>s whatsoever hidden somewhere in your .JAR, in a nested .JAR, or somewhere in an .OBR.
