First of all, I can’t find how to contact support.

I don’t have more clues, this is the entire relevant output
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':publishPlugins'.
> Failed to post to server.
  Server responded with:
  Server side processing failed. Please email support with reference hash: 324daf

Failing code available here so maybe you can take a look and tell me what fails: https://github.com/albertonavarro/loggergenerator-gradle-plugin

My credentials are safe in my .gradle repo in my user folder, double checked.

Any clues?

Thanks

Alberto.
