Everything works with the usual projects.
Beside that, it looks like the fix for issue #933 also fixed the issue described in GRADLE-3555 and Sudden ClassNotFound exceptions, sometimes related to changed dependencies.
I hoped that those would have the same root cause and it looks very good so far.
I triggered multiple builds on our CI but without any failures at all. I can’t be 100% sure since the problem wasn’t reproducible reliably but I’m tentatively ecstatic.
Thanks a lot!
