title: Running a command in a Grunt Task
body: <p>I'm using <a href="https://github.com/cowboy/grunt">Grunt</a> (task-based command line build tool for JavaScript projects) in my project. I've created a custom tag and I am wondering if it is possible to run a command into it.</p>
  
  <p>To clarify, I'm trying to use Closure Templates and "the task" should call the jar file to pre-compile the Soy file to a javascript file.</p>
  
  <p>I'm running this jar from command line, but I want to set it as a task.</p>
