title: Android build from command line in Windows
body: <p>I would like to build an Android project from command line instead of using Eclipse. I have installed ant on my Windows Vista, and I would like to run <code>ant release</code> but I can't find the file <code>build.xml</code> in the root directory of my Android project.</p>
  
  <p>The project has been created using Eclipse. Is there a particular reason why the file <code>build.xml</code> doesn't exist ? How to find/generate it please ?</p>
  
  <p>Thanks.</p>
