Update: The build requires now Java 11 so the GH-action workflows have to be adjusted

Looks good to me.

I think we can switch to building with Java 11 without problems. I already build with JDK 11

I did not find a changelog, too.

@litetex @TobiGr This, probably. Two issues under AGP.

This breaks compat with pure IDEA without google's telemetry android flavour.

Idea users need to revert this when they want to do anything.
The AGP 4.2.2 version works just fine FYI, would it be acceptable to revert this until Idea supports AGP 7.0?

Only in the early access builds though.

It'd just be nice to be a bit more conservative with major revision bumps like these in the future then.
