title: IntelliJ2-IDEA get Maven-2 to download source and documentation
body: <p>I have a spring mvc project setup using maven in IntelliJ.
  While I was setting the project up, IntelliJ asked me if I wanted to download the source and documentation. In order to save time at that point I did not select this option. However now I would like to download some of the source if not all. Does any one know where how to accomplish this in IntelliJ for a project that has already been setup?</p>
  
  <p>The question is specific to how to do this with intelliJ since I would like all the mouse over and documentation features in IntelliJ to show me the source / documentation when needed.</p>
  
  <p>Thanks,</p>
