title: How can I edit the content of .properties file?
body: <p>I am using Jenkins server with perforce. My build get stored in a local repo path in ".zip" format which contains all the file including (say) <em>abc.properties</em>. This file contains data:</p>
  
  <pre><code>#Thu Jun 09 12:13:14 MSD 2011
  BuildType=dev
  FrameworkBuild=200
  ProductVersion=4.40.00
  SoftwareFeatureID=34670101
  BuildNumber=0
  FrameworkVersion=2.47.00
  </code></pre>
  
  <p>In this <em>abc.properties</em> file <code>BuildNumber = 0</code> is a default value(set in perforce). My old build system updates the <code>BuildNumber</code> value with current build number in the zip file.</p>
  
  <p>How can I achieve the same in Jenkins.</p>
  
  <p>Thanks in advance.</p>
