title: Eclipse error: This project needs to migrate WTP metadata
body: <p>We started a Web Project in Eclipse 3.2 a ways back and we've since upgraded to Eclipse 3.4 but now the Project has the error:</p>
  
  <p>"This project needs to migrate WTP metadata"</p>
  
  <p>We've tried right-clicking and doing the "quick-fix" which is in fact to Migrate WTP Metadata. Unfortunately nothing happens and the error remains. </p>
  
  <p>We can delete that error from the Problems and everything works as it should, however, every time we re-import the project from source control, the error re-appears. Any ideas on how to permanently get rid of this error or how to ACTUALLY migrate WTP metadata?</p>
