Are Gradle developers using IntelliJ for running and debugging tests? My IntelliJ always gets stuck when doing a "Step Over" through the debugger and I'm curious if anyone else had this problem already?

Are you talking about developing on the Gradle project itself? (because on my own projects, I never experienced that)

Yes, developing Gradle project itself

Then maybe moving the question to #C03PU37T8TZ might be better. :-)

I also hit that issue with Hibernate ORM from time to time, so not sure if this is a general IntelliJ issue

I've had this issue when the source code used to step over wasn't what was actually executed. I can't remember the exact details, but it has happened.
