title: Apache Ivy dependencies force="true" does not work
body: <p>My project has commons-codec as a dependency and uses Ivy.<br/>
  Some other dependencies need commons-codec-1.6 and 1.2.<br/></p>
  
  <p>Now my problem is that Ivy evicts my version(1.4) and instead uses 1.6.<br/>
  <code>&lt;dependency org="commons-codec" name="commons-codec" force="true" rev="1.4" /&gt;</code></p>
  
  <p>Why doesn't force work? Has anyone encountered this yet?</p>
  
  <p>FYI i have used this before and it worked...</p>
