title: delete the 'target' directory after build
body: <p>i know this is probably frowned upon by maven lovers, but the whole 'target' directory is a waste of space in the context of our program and it's deployment. we have other build processes responsible for creating the actual deployment and i currently manually delete the target dir after every maven build, so that its contents don't interfere with my file searches etc...</p>
  
  <p>is there a way to delete this dir automatically at the end of a maven build/install?</p>
  
  <p>thanks, p.</p>
