If you have a Scala only project, you need to configure sourceDirectory
and testSourceDirectory
as is ( required by maven-eclipse-plugin not by maven-scala-plugin ) :
<build>
<sourceDirectory>src/main/scala</sourceDirectory>
<testSourceDirectory>src/test/scala</testSourceDirectory>
...
For more configuration options or information take a look at the site of maven POM Overview (Technical Project Descriptor)
If you have a mixed Java/Scala project with code into separated root directory (like src/(main|test)/scala and src/(main|test)/java) : <!-- Adds src/main/scala and src/test/scala as source folders, from http://groups.google.com/group/liftweb/browse_thread/thread/3dac7002f9e59546/3918bba2f7a92cd3?pli=1 --> org.codehaus.mojo build-helper-maven-plugin add-source generate-sources add-source src/main/scala add-test-source generate-sources add-test-source src/test/scala
