PlantUML java automation

Question

Currently I am working on a project that should represent all classes via PlantUML's. I have heard that this UML could be generated automatically using Maven. But unfortunately all articles and repos are already 6-9 years old and therefore outdated.

Would anyone have a tutorial for me?
