title: Eclipse fails to import Maven project
body: <p>I tried to import a multi-module Maven project into Eclipse using the option "Existing Maven Project" from the Import menu.</p>
  
  <p>I got this error:</p>
  
  <pre><code>Could not update project nbsocialmetrics-frontend configuration
  java.lang.NullPointerException
  </code></pre>
  
  <p>In the problems pane I saw this error:</p>
  
  <pre><code>Project configuration is not up-to-date with pom.xml. 
  Run Maven-&gt;Update Project or use Quick Fix. nbsocialmetrics-backend     line 1  Maven Configuration Problem
  </code></pre>
  
  <p>However when I ran Maven->Update Project I just kept getting this error:</p>
  
  <pre><code>Unable to update Maven configuration
  Could not update project nbsocialmetrics-frontend configuration
  java.lang.NullPointerException
  Could not update project nbsocialmetrics-backend configuration
  java.lang.NullPointerException
  </code></pre>
  
  <p>The last repository checkin on this project had no issues so I can't figure out why Eclipse won't import it.</p>
