body: <p>When I try to export an apk of my Android application I get this error :</p>
  
  <pre><code>Export Wizard Error   
     Errors occurred during the build
  
  Problems occured when invoking code from plug-in: "org.eclipse.resources".

  <p>The error is really strange, because I can run/debug the application with the emulator or a device. Is there something to do to prevent this error ?</p>
