title: IntelliJ Idea 14: cannot resolve symbol spark
body: <p>I made a dependency of Spark which worked in my first project. But when I try to make a new project with Spark, my SBT does not import the external jars of org.apache.spark. Therefore IntelliJ Idea gives the error that it "cannot resolve symbol". 
  I already tried to make a new project from scratch and use auto-import but none works. When I try to compile I get the messages that "object apache is not a member of package org". My build.sbt looks like this:</p>
  
  <pre><code>name := "hello"
  version := "1.0"
  scalaVersion := "2.11.7"
  libraryDependencies += "org.apache.spark" % "spark-parent_2.10" % "1.4.1"
  </code></pre>
  
  <p>I have the impression that there might be something wrong with my SBT settings, although it already worked one time. And except for the external libraries everything is the same...
  I also tried to import the pom.xml file of my spark dependency but that also doesn't work.
  Thank you in advance!</p>
