title: Eclipse Google Plug-In doesn't start server for web application
body: <p>I want to try the Google Eclipse plug-in for the Google App Engine, but I get stuck in the tutorial...</p>
  
  <p>I want to start the web application from the Google tutorial, but when I click on "RUN AS > Web Application", I only see this message on the console:</p>
  
  <pre><code>Usage: &lt;dev-appserver&gt; [options] &lt;war directory&gt;
  
  Options:
   --help, -h                 Show this help message and exit.
   --server=SERVER            The server to use to determine the latest
    -s SERVER                   SDK version.
   --address=ADDRESS          The address of the interface on the local machine
    -a ADDRESS                  to bind to (or 0.0.0.0 for all interfaces).
   --port=PORT                The port number to bind to on the local machine.
    -p PORT
   --sdk_root=root            Overrides where the SDK is located.
   --disable_update_check     Disable the check for newer SDK versions.
  </code></pre>
  
  <p>What's the problem? It seems like the command to start the server is wrong, but I haven't edited it... can someone help?</p>
