We have stopped publishing to Maven Central for the time being as our existing configuration stopped working.

Reference: Publishing Java packages with Gradle: You can use Gradle to publish Java packages to a registry as part of your continuous integration (CI) workflow.

We are calling for help. We are looking for someone to contribute a CI workflow as well as a gradle configuration that allows us to publish our releases automatically.

The process needs to be automated: with every release on GitHub, we should get that the artefacts are signed, uploaded, published and made available to our users without manual intervention.
