By the way... there is nothing that is immediately beneficial.

• If I had to mention it, it would probably be Unnamed Patterns and Variables.
  • However, this is not possible with the current unified naming format for detection, so it will probably not be practical until much later. PMD will address it first and then PMD will encourage it. Don't do anything unnecessary and deal with it after it happens.
• The assumption is that we don't need to do anything special.
  • Correspondence between packages and directories will be mandatory and strict. We don't think anyone would make such a mistake.

Of course it is possible to compile and execute. However, the latest maven-dependency-plugin does not yet support Java22.

If you can't migrate including CI tools, there's no point. This matter will be pending for a short period of time.
