title: How to fix m2eclipse plugin?
body: <p>I have java maven project in Eclipse that depends from other projects and for near 1000 library jar.
  But I cannot use m2eclipse at all. 
  For create Eclipse project is use eclipse maven plugin like:</p>
  
  <pre><code> mvn eclipse:eclipse -Dwtpversion=1.5
  </code></pre>
  
  <p>It works well. But when I go to Eclipse and click on m2eclipe - update dependencies - all library jars disappear!
  So for work I have disabled java projects as maven in Eclipse. I suppose that there is some problem with eclipse internal variables. Does it correct? What have I check? Does exist some log? Or this is common bug of m2eclipse plugin?
  Thanks.</p>
