Scala warnings, IntelliJ and compiler flags

Question

I\'m currently giving the IntelliJ Scala plugin a spin and one thing is bugging me a wee-bit. I get 3 warnings when compiling.

Warning: scala: Recompiling 4 file         


        

Answer 1

In IntelliJ 14:

1. Bring up preferences Intellij IDEA > Preferences or cmd + ,
2. Look up Scala Compiler. Alternatively, it's under Build, Execution, Deployment > Compiler > Scala Compiler
3. Check the option for Deprecation warnings
