The work of fge found a new owner / maintainer. All fge-dependencies have been moved to java-json-tools groupId.

Hi @sdoeringNew, thanks for the PR, where can I read about that change? I have looked at the fge project and I can't find any mention to the java-json-tools .

You can't find it there anymore.

Look at: https://github.com/fge/json-schema-validator It redirects to the new maintainer: https://github.com/java-json-tools/json-schema-validator

And you can see fge's last update on the README.md looking for a new maintainer: https://github.com/java-json-tools/json-schema-validator/commit/fd781ef2
