Play framework 2 running unit tests in Intellij IDEA 13

Question

There are two very similar questions here and here . I created a project with play new and ran play idea . The tests run with the play test command and when I try to run them in IDEA I get the following stacktrace.

I have tried turning off the external compiler server in Settings (IDE) -> Scala, invalidating cache, and get the same exception. This is jetbrains post about the compiler server.

Answer 1

In my case, the problem has not solved with 133.331. IntelliJ 13 still does not compile test codes.

I think it's due to external build, because there is no problem with IntelliJ 12 of which external build option is off.

Answer 2

将IntelliJ从13.0.1 133.330更新到13.0.1 133.331为我解决了这个问题。
