title: Exclude directories & subdirectories from validation in Eclipse
body: <p>How do I exclude a folder AND its sub-directories from validation in eclipse? I know that you can right click on a folder in Package Explorer and select Exclude Validation, but if you have sub-directories under it, you'd have to this for each and it isn't ideal for generated directories or ones with many sub-folders.</p>
  
  <p>Any plug-ins that might be able to do this?</p>
