  -- pls check the different file names: I think they should be the same for both variants
  -- should we also add the version info to the .aar file?
  -- should we also add the cumulocity-clients-kotlin-debug.aar?

Seems good to me.

-- should we also add the version info to the .aar file?

Yes.

-- should we also add the cumulocity-clients-kotlin-debug.aar?

No opinion on that one. Guess the release aar is enough?

Not an expert in the use of workflow_call, but seems about right to me.

finally it is working:

• https://github.com/SoftwareAG/cumulocity-clients-kotlin/releases/tag/v10.18.0-269
  @joerghartmann @MarkJMReynolds-SAG pls review

Update: Nope, ignore me, I figured it out.

finally it is working:

Looks mostly reasonable to me, but I suspect something is still not right - looking at the archived assets in the workflow -
- aar = 552k
- jar = 593k

Then in the release itself for build 269 -
- jar = 593k 🆗
- aar = 779 Bytes 😕

Maybe you really do mean this, in which case I'll approve, but I can't see intent for anything other than "pass the files along exactly as-created", in which case L62 in release.yml seems to be pointing at the wrong file, doesn't seem to match the change on L47 of build.yml IMO.
