title: How to exclude file on maven release:prepare and release:perform?
body: <p>I am using maven to release/tag my projects, and I am using some propery files and want mvn:prepare to exclude those under release. I tried using the following command:</p>
  
  <pre><code>mvn release:prepare -DpreparationGoals="clean install"
  -DcheckModificationExcludeList=props.properties
  </code></pre>
  
  <p>But it still gives me the following error:</p>
  
  <pre><code>[INFO] Cannot prepare the release because you have local modifications :
  [props.properties:unknown]
  </code></pre>
  
  <p>So the question is: how can ACTUALLY make maven mvn:release skip checking for certian local modifications? Thanks for your time.</p>
