title: Classpath entry org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER will not be exported
body: <p>I'm getting this warning in Eclipse:</p>
  
  <blockquote>
    <p>Classpath entry org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER will not be exported or published. Runtime ClassNotFoundExceptions may result</p>
  </blockquote>
  
  <p>After searching I found that I need fix export. I did it.</p>

  <p>But this warning persists!
  What else can be done to fix it?
  Thanks.</p>
