JsonFormMLSAssetGenerator failing with "SourceSet with name 'main' not found."

Running JsonFormMLSAssetGenerator fails with "SourceSet with name 'main' not found."

There are discussions on reddit that running standalone java may have been disabled in recent Android studio versions.

It may be time to move it to its own application project ?
