Hi Niels, even if I’m happy it seems to be working for you, it’s still odd that you were having such issues. Usually, you don’t need to comment out the code generation as in 90% of the times it doesn’t really change anything. When you do the build, it just generates new versions, which are identical to the existing ones.
And usually, you simply set a breakpoint and then run the test directly from IntelliJ (If you want to debug tests executed from Maven during the build, that requires some extra effort) Chris From: Niels Basjes <ni...@basjes.nl> Date: Friday, 6.

I have just 1) Done a full local install into my local maven repo (~/.m2) 2) Commented out the entire code-generation module 3) Now it all works very well.
