If you get this error when launching a Run Configuration in Eclipse with the IAM (Maven) >plugin:

Referenced classpath provider does not exist: >org.maven.ide.eclipse.launchconfig.classpathProvider

It’s probably because your Run Configuration was created on an old project, and has bad >entries in the Classpath section. The solution is to delete the Run Configuration and create >a new one.
