Intellij: Debugging does not work with Play Framework

Question

I have problems for some time with debugging in Intellij (Ultimate 2019.2).

If I set Breakpoints and restart Intellij, or it reloads after a code change, all the Breakpoints work as expected:

But if I set the Breakpoints when the Play server is running, only a few of them still work:

Is this a bug, or is my configuration wrong?

Try this

File -> Invalidate Caches/Restart

Intellij keeps reloading stuff, breakpoints become active only when it's truly sure, no false positives here.

Usually I do, start the server then debugger and make sure endpoints are active before I make the request.

what do you mean _I start the server then debugger_? Do you run first the play configuration and then attach a debugger? – pme Nov 08 '19 at 15:11
yes, but that's all I have. The state you mention happens intermittently, usually resolves itself given some time, extreme cases I invalidate cache. – Gagandeep Kalra Nov 09 '19 at 00:02

Did you try debugging from sbt? – Gagandeep Kalra Nov 09 '19 at 00:03
Debugging with sbt works - so it seems to be a problem with Intellij. – pme Nov 10 '19 at 16:18

As it worked with plain sbt (Thanks for the hint of @Gagandeep Kalra), I asked for support of Intellij:
