SBT and Play work together great and activator run recompiles incrementally, this setup is OK.<p>The issue is with IntelliJ -- when I want to run Play app from IntelliJ, not from command prompt, to get easier debug support when running the app or junit tests. Running tests from IntelliJ is more convenient than using activator shell.<p>Yes, I could provide -jvm-debug flag to the activator command line but this works only when fork:=false, which can&#x27;t be always used.
