title: Unresolved dependency issue when compiling spark project with sbt
body: <p>I am trying to compile with <code>sbt 0.13.8</code> a very simple spark project whose only function is</p>
  
  <p><strong>Test.scala</strong></p>
  
  <pre><code>import org.apache.spark.SparkContext

    def main(args: Array[String]) {
      val logFile = "YOUR_SPARK_HOME/README.md" // Should be some file on your system
      val conf = new SparkConf().setAppName("Simple Application")
      val sc = new SparkContext(conf)
      val logData = sc.textFile(logFile, 2).cache()
      val numAs = logData.filter(line =&gt; line.contains("a")).count()
      val numBs = logData.filter(line =&gt; line.contains("b")).count()
      println("Lines with a: %s, Lines with b: %s".format(numAs, numBs))
    }
  }

  <p>How could I solve this dependency issue?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I have followed the @mark91's advice:</p>
  
  <ul>
  <li>change scala version to <code>2.10.5</code></li>
  <li>change the spark dependency to <code>libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "1.2.0-cdh5.3.2" % "provided"</code>.</li>
  </ul>
  
  <p>However I still get an unresolved dependency in org.scala-lang#scala-library;2.10.4 :</p>

  <p>Do you have any idea of why I get this problem?</p>
