title: Only show warnings from some folders in eclipse
body: <p>I am working in a larger Java codebase in eclipse, which currently issues around 7000 warnings. However I am working in rather isolated parts, in a few specific source folders and namespaces. I would like eclipse to only show warnings for my modules in the Problems tab, and not for the entire codebase. Currently it shows the first 100 warnings which are not related to my modules. Is this possible?</p>
  
  <p><strong>Update</strong>
  Thanks for all the nice answers. Updated the question a bit to make it clear that I am talking about multiple, albeit a rather small number, of folders and namespaces.</p>
