title: Eclipse loops endlessly: Invoking 'Maven Project Builder'
body: <p>Ugh!  My Eclipse is stuck in an endless loop:</p>
  
  <ul>
  <li>No operations to display at this time</li>
  <li>Refreshing Workspace Building</li>
  <li>Workspace. Invoking 'Maven Project Builder' on /MobileWebApp</li>
  </ul>
  
  <p>The building workspace never gets past 58%.</p>
  
  <p>Details:</p>
  
  <p>Google's GWT provides a sample app MobileWebApp.  They <a href="http://googlewebtoolkit.blogspot.com/2011/09/working-with-maven-and-requestfactory.html" rel="noreferrer">suggest adding it to Eclipse</a> via File > Import > Checkout Maven projects from SCM.</p>
  
  <p>I followed the instructions in <a href="http://www.shareyourwork.org/roller/ralphsjavablog/entry/eclipse_indigo_maven_and_svn" rel="noreferrer">this blog</a> for adding the plugins for m2e, subclipse, and the m2e-subclipse connector.</p>
  
  <p>After installing the plugins, I imported the sample project via File > Import > Checkout Maven projects from SCM and <a href="http://google-web-toolkit.googlecode.com/svn/trunk/samples/mobilewebapp" rel="noreferrer">this URL</a>.</p>
  
  <p>The import seemed to complete ok and Eclipse doesn't display any markers.  But now I have this endless refreshing and building and have no clue what is causing it or how to fix it.</p>
  
  <p>Versions:</p>
  
  <ul>
  <li>Eclipse Indigo 3.7</li>
  <li>m2e 1.0.100 </li>
  <li>m2e connector for build-helper-maven-plugin 0.14 </li>
  <li>Maven SCM handler for Subclipse 0.13</li>
  <li>Subclipse 1.6.18</li>
  <li>Subclipse Client Adapter 1.6.12</li>
  </ul>
  
  <p>Any advice is greatly appreciated.</p>
