2021 is calling 
on a more serious note … we are actually experiencing this, too … i am currently challenging our build engineers with what i need to upgrade SonarQube from 8.9 (java11 optional) to 9.x (java11 mandatory)
The documentation here explains a (Jenkins) way for maven (but not for gradle) and the challenges mentioned here in this thread surface in our builds. (the gradle task dependencies, even optimized already, need some -x administration)
If anything, would it maybe be possible to address the documentation of working ways for both tools (maven + gradle) in the beforementioned existing docs? 
it would be nice to be able to use that as a reference for ppl asking 
(for reference: here you can find a newer episode of the same)
