IntelliJ 12: showing Play 2.1 / Scala compilation errors in the project navigator?

Question

I have IntelliJ 12 Ultimate and I use Play Framework 2.1 with Scala (I love them both)

One thing that I skip from Eclipse is to view project files annotated with a red mark if they do not compile.

I tried to enable settings> Compiler> Use external assembly> Make project automatically

This showed no errors (even in the Problems panel)

I tried the plugin "Eclipse Mode". Also does not seem to have any effect. “Compilation problems not found” in the “Problems” panel, despite obvious problems with the code (renamed method in xxx without using refactoring)

Suggestions will be highly appreciated

Answer 1

I had exactly the same problem, and I just solved it, making sure IntelliJ was not in power saving mode, because code analysis was disabled in this mode.

You can see whether it is enabled or not in the status bar in the lower right corner of IntelliJ.

I hope you are so simple.
