title: Eclipse can't delete lib.jar
body: <p>When I try to clean my projects I am now getting two errors that stops the build process...</p>
  
  <p>Could not delete: D:\myworkspace\library\bin\library.jar.
  Could not delete 'D:\myworkspace\google-play-services_lib\bin\google-play-services_lib.jar'.</p>
  
  <p>I am running Eclipse as administrator on my Windows 7 computer.</p>
  
  <p>I have been updating all of my libraries recently in order to use Google Cloud Messaging but I have no idea if this has anything to do with it.</p>
  
  <p>If I delete the jar files manually, then start eclipse and clean it will run ok.  But now I need to do this anytime I want to recompile.</p>
  
  <p>I have googled this error but I can't find anything on it.</p>
  
  <p>Thanks,
  Gary</p>
