I have IntelliJ 12.1.3 and installed the following:
I then went ahead and created a Play project within IDEA (via Java -> Play 2 Module for Java).
Everything appears to go well with the Java files. However, I noticed that the Build.scala file has highlighting errors.
Question is: Is still supposed to have highlighting errors since it is a Scala file? If not, am I missing some configuration I need to do?
BTW, I also enabled Scala type-aware highlighting (where the 'T' is showing on the bottom right status bar), but still no go.
The Scala facet under Project Settings -> Modules has no errors and I left everything as default. The Compiler Library is set at Scala 2.10.0.
sorry for long response. Build.scala has highlighting errors because it is a SBT build file and right now there is no support for SBT specific stuff. We are working on plugin for SBT and it will be available soon.
