Hi Matthias! I went through that thread but as I'm just using the `apache/flink` docker image for testing I honestly couldn't figure out how I would do that since I don't have a pom file to edit. If it's possible to do it through the configuration I'd be glad if you could point me out in the right direction.
Pretty evident I don't have a lot of experience with mvn or "modern" Java in general. :-) Thanks!
