With 0.2.18767, I had a Scala module set up with Scala code in src/main/scala. This is the layout that the Scala Maven plugin expects (and is very useful for the continuous compilation and console; mvn scala:cc and mvn scala:console)
Since I've switched to 0.2.19059, the Scala directory no longer works as a source directory. Steps to reproduce:
a) Open Project Settings | Modules
b) Open my Scala module (called scala, which has an attached Scala facet)
c) Select the src/main/scala directory in the tree on the right hand side, and click "Sources"
d) src/main/scala appears under the list of source folders, but is highlighted red, rather than blue, and Scala files present in it aren't recognized as source
This only appears to be a problem for that specific directory: src/main/scala2, src/scala, scala, src/main/java, etc. all work fine. And it's to do with the name, not the directory... completely deleting the directory and recreating the structure still has the same problem.
My project file contains:
which looks pretty standard to me.
Any idea what's going on?
