title: Double source folder in eclipse when creating new maven project
body: <p>I'm using Eclipse kepler to make a maven 2 or 3 project. I used the "webapp" archetype to start with a clean empty project, and I followed some simple helloworld tutorials. However, I noticed that in eclipse my src folder is shown twice, as seen in the picture below:</p>
  
  <p><img src="https://i.stack.imgur.com/qXVXI.png" alt="enter image description here"></p>
  
  <p>This is very undesirable, it takes up additional space and they are not very well synchronized, for example the src on the bottom contains the <code>"webapp"</code> folder, but the src on top doesn't. What's the deal with this double structure? Colleagues of me, who use an older version of eclipse, don't see the <code>"java resources"</code> subtab but I can't find a way to turn it off.</p>
