title: Eclipse Android gen already exists but is not a source folder
body: <p>I am getting the following errors when I try to load an Android project in Eclipse that was working just fine last week.
  Any ideas?</p>
  
  <pre><code>[2012-03-16 09:29:43 - MyProject] /MyProjectName/gen already exists but is not a source folder. Convert to a source folder or rename it
  </code></pre>
  
  <p><strong>Note</strong> that I have tried to clean the project several times, even restarted but it still gives me this errors.</p>
