I am keeping my Scala sources under src/main/resources/installed/bin/src because my applications installs them as scripts. I have set Build Path -> Use as Source Path, and I have added the Scala nature to the project. I can see the Scala preferences in the project settings.

For some reason Eclipse seems to think my Scala sources are Java or something else as I have tons of errors (see below).

In the Eclipse Package Explorer the Scala files have the [S] icon on them, so some part of Eclipse thinks they are Scala files.
