title: Eclipse Project with Scala Plugin, Maven and Spark
body: <p>I have Eclipse Kepler, I have installed the Maven and Scala plugins. I create a new Maven project and add the dependency</p>
  
  <p>groupId: org.apache.spark
  artifactId: spark-core_2.10
  version: 1.1.0</p>
  
  <p>as per current doc at <a href="http://spark.apache.org/downloads.html" rel="nofollow">http://spark.apache.org/downloads.html</a>, all is fine, the jars for Scala 2.10 are also added to the project. I then add the "Scala Nature" to the project, this adds Scala 2.11 and I end up with the following error</p>
  
  <p>More than one scala library found in the build path (C:/Eclipse/eclipse-jee-kepler-SR2-win32-x86_64/plugins/org.scala-lang.scala-library_2.11.2.v20140721-095018-73fb460c1c.jar, C:/Users/fff/.m2/repository/org/scala-lang/scala-library/2.10.4/scala-library-2.10.4.jar).
  At least one has an incompatible version. 
  Please update the project build path so it contains only compatible scala libraries.</p>
  
  <p>Is it possible to use Spark (from Maven) and Scala IDE Plugin together? Any ideas on how to fix this problem?</p>
  
  <p>Thanks for your help. Regards</p>
