title: Scala IDE can't resolve dependeices
body: <p>I'm using the Scala IDE and I have the following build.sbt:</p>
  
  <pre><code>name := "hello"
  
  version := "1.0"
  
  scalaVersion := "2.9.1"
  
  libraryDependencies += "org.apache.commons" % "commons-lang3" % "3.3.2"
  </code></pre>
  
  <p>My class is:</p>
  
  <pre><code>object TextSplitter {
  
    def splitHalf(inputString: String) = {
  
        StringUtils.isEmpty(inputString)
    }
  }
  </code></pre>
  
  <p>Eclipse can't resolve the dependency for StringUtils. In fact, I keep having problems with Eclipse/SBT to import anything outside the scala.* package.</p>
  
  <p>I'm new to Scala, just want to try it out by building an actual example, but looks like I can't.
  Any idea how to resolve this?</p>
  
  <p>Thanks</p>
