title: m2e gives inscrutable "project read error"
body: <p>I just started to use m2e to try to build the sample travellog elastic beanstalk project. On the console I'm getting "[ERROR] Project read error".</p>
  
  <p>This also appears in red on the "Dependency Hierarchy" tab. </p>
  
  <p>What does this mean and how do I find out more details?</p>
  
  <p><strong>Edit: Adding pom.xml</strong></p>
