This is similar to #200.

It's been more than a year since the last release published to maven (4.1.0) and since then there have been multiple changes made and merged to master:

• 4.1.0 tag: https://github.com/timols/java-gitlab-api/tree/4.1.0
• master: https://github.com/timols/java-gitlab-api/tree/master

@timols can you please release the next version? Thanks!
