title: Filtering available Gradle tasks by task group
body: <p>With the command <code>gradle tasks</code> one can get a report of all available tasks. Is there any way to add a parameter to this command and filter tasks by their task group.</p>
  
  <p>I would like to issue a command like <code>gradle tasks group:Demo</code> to filter all tasks and retrieve a list of only those tasks that belong to the task group called <code>Demo</code>.</p>
