title: Change default path of android.jar during ant build
body: <p>I want to use a modified android.jar(not inside android-sdk) for a particular project whenever I build project by ant script.</p>
  
  <p>This modified android.jar is placed  inside my project directory.I have found that in default build.xml that is inside <code>sdk/tools/ant/</code> one varible that is <code>"project.target.android.jar"</code> is being used for the path of <code>android.jar</code> so I have tried to override the value of <code>"project.target.android.jar"</code> variable inside my ant.properties (that is inside my project directory) and set it to my new path of android.jar but it is not working.
  Can anyone help me to change this path??</p>
