title: How to install a plugin using JRuby?
body: <p>I'm trying to install the jQuery Grid Rails Plugin. I'm using JRuby 1.7.0. I tried this command with no luck:</p>
  
  <pre><code>jruby -S plugin install git://github.com/ahe/2dc_jqgrid.git
  rails plugin install git://github.com/ahe/2dc_jqgrid.git
  </code></pre>
  
  <p>And some others...</p>
  
  <p>I know that some commands change for JRuby. Commonly I prepend <code>jruby -S</code> to the command but it's not working with plugin install. Any suggestion?</p>
  
  <p>Regards.</p>
