JDL import: This Generator is empty

JDL import fails with existing .jdl

I created a new v8.0-beta app and try to import an existing .jdl which worked fine on v7.9.2. I had to add the expression 'with builtInEntity' for the relationships with User, that's all I changed.

I copy/pasted my .jdl into jdl studio and there are no errors (excluded 'with builtInEntity' changes).

The following error: ERROR! This Generator is empty. Add at least one method for it to run.

I think I'm missing the application declaration in the .jdl. I'll check and try to apply the docs from my side.

Complete error
