Scala IDE for Eclipse

All Maven projects wishing to use Scala must first ensure that their project is set up and builds correctly on the command line. Please see the maven-scala-plugin for more details.

Support for Maven projects within the Eclipse IDE is provided by two alternative Eclipse plugin options:

• With M2Eclipse (supported version via m2e-scala)
• With Maven CLI
• With IAM

You should never, EVER use a different plugin version from the version of scala you're using in Maven. The Scala IDE for eclipse is tied to a particular version of Scala and mismatched class versions can cause major issues on large projects.
