title: How do you clear the validation errors in Eclipse?
body: <p>I accidentally clicked on "Validate" for all of my projects (instead of going to Team > synchronize...) and I have several validation errors and tons of warnings.</p>
  
  <p>I can't figure out how to clear these so it goes back to just having the standard errors.</p>
  
  <p>(One way is to go to "Configure Contents" of the "Problems" view and deselect the validation errors, but I know they're still there, just hidden... it bugs me that they're not actually removed)</p>
  
  <p>I've tried restarting eclipse, tried cleaning all projects but that doesn't clear these validation errors.</p>
