title: IntelliJ External libraries package X does not exist
body: <p>I added some external libraries to my project and in the editor intelliJ is not giving me any errors, when I compile it though it gives me errors saying:</p>
  <blockquote>
  <p>[ERROR] /C:/Users/martijn2/IdeaProjects/fakePing/src/main/java/mpolder/fakePlayer.java:[3,26] package com.skionz.pingapi does not exist</p>
  <p>[ERROR] /C:/Users/martijn2/IdeaProjects/fakePing/src/main/java/mpolder/fakePlayer.java:[4,26] package com.skionz.pingapi does not exist</p>
  <p>[ERROR] /C:/Users/martijn2/IdeaProjects/fakePing/src/main/java/mpolder/fakePlayer.java:[5,26] package com.skionz.pingapi does not exist</p>
  </blockquote>
  <p>How do I import API's into my intelliJ and make them package with all my other stuff?
  I use IntelliJ + Maven</p>
