Merge error not comprehensible

[staeff777]

I'm receiving a merge error which I cannot which I cannot assign to any source.

Do you have any advice how to narrow down the problem?

[error] 1 error(s) were encountered during the merge:
[error] java.lang.RuntimeException: 
[error] Deduplicate found different file contents in the following:
[error]   Project name = myproject, target = 
[error]   Project name = myproject, target = 
[error]   Project name = myproject, target = 
[error]   Project name = myproject, target =

@staeff777 Do you have a repro steps that we can use to reproduce this issue on our machines?

It happend during a scala 2.12->3 mirgration. I hoped that this might give you a clue for me.

I'll investigate deeper and try to create a minimal example.

Sorry for the long delay. I finally found the source.

I had a ./lib folder in the project root, with just some native libraries. No extra references in the build.sbt. It was historically used for unmanaged jars, but meanwhile all are managed.

This caused the error. I renamed the lib-folder and everything works fine.
