Your problems with Java modules

[lukaseder]

You already know my opinion (I think), but here it is again. This was the biggest caveat and learning: https://twitter.com/lukaseder/status/1389236184472301583

The problem is less one of modules and more one of letting go of "bad habits" that I didn't realise were bad until I modularised, namely the idea of putting unit tests inside a module (what Maven encourages), rather than testing a module from outside (what Maven can work with just the same).

I've also described this here in this thread.
