title: Invalid file: android-sdk-linux/extras/android/support/v7/appcompat/build.xml
body: <p>I'm trying to create an Android application only from the command line, build with <code>ant</code>
  I've made these steps:</p>
  
  <ol>
  <li>downloading the appcompat v7 and v4</li>
  <li>I've run <code>android update project --target 1 --path . --library ../../Downloads/android-sdk-linux/extras/android/support/v7/appcompat</code></li>
  </ol>
  
  <p>Now when I run the command <code>ant debug</code> I get the following error message:</p>
  
  <pre><code>[dependency] ------------------
  [dependency] Ordered libraries:
  [dependency] 
  [dependency] ------------------
       [echo] ----------
       [echo] Building Libraries with 'debug'...
  
  BUILD FAILED
  /home/xxxx/Downloads/android-sdk-linux/tools/ant/build.xml:601: Invalid file: /home/xxxx/Downloads/android-sdk-linux/extras/android/support/v7/appcompat/build.xml
  </code></pre>
  
  <p>I've tested also with this <a href="https://github.com/commonsguy/cw-omnibus/tree/master/ActionBar/AppCompat" rel="nofollow">project</a></p>
  
  <p>Using that, I got exactly the same error, and indeed the file "build.xml" is not present in that directory.</p>
  
  <p>I'm specifically looking for command line answers as the goal is to understand "the magic". Does the problem come from me, or am I missing something ?</p>
