Note: I only have JDK 17 installed, which might be the cause for [WARNING] system modules path not set in conjunction with -source 11.

is fixed in #450

[derTobsch]

The module warnings are, because the modules has not been build to this time and therefore the warning or I am wrong?

Thank you. Yes, that fixes that warning.

Hm, yes, could be. How would one be doing this then normally? Is there a way to build it in a way that all dependencies are built beforehand? It does not seem correct to me to always get this warning, but I don't know after all whether this is to be expected.
