title: Is there a simple CLI Java linter?
body: <p>I've been trying to find a Java linter capable of running on the CLI that is separate from Eclipse that I can call as a commit hook for git or from our automated build script. Does such a thing exist?</p>
  
  <p>Ideally it needs to check for unused imports and variables, that style guidelines are followed, exceptions are used properly, etc. Though some subset of those features would be better that what we have now - nothing!</p>
