The issue is something else. I had only checked the Eclipse Error Log and
didn't see anything, but now I noticed that Errors are logged to the
Console when I launch the migration task:

I tried to debug into this but could not find any trivial problems..

I am using I am using capella_studio-1.0.0-2015-11-03_00-09-20 and would
like to regenerate code in the capella master branch.

Thanks for any help.
Felix
