Hey all, Please enlist to #5101 as it is the follow up actions post 1.6

@emmanuelbernard Would you consider including #9738 in the list?
Bootstrap (and thus unit testing with @QuarkusTest) does not work in Gradle projects when invoking tests from within an IDE.

@jskovjyskebankdk yes that makes sense CC @glefloch

Yes I'm still working on it, I will open a draft PR ASAP.

I think https://github.com/quarkusio/quarkus/issues/11388 is essential for beginners to be able to use gradle safely. Without it Gradle users will experiencing problems that maven users have not seen before and thus might frustrate them quickly.

This was in the 1.7 roadmap, but it was missed.

What is the new expectation?
