title: How to debug Play application using activator?
body: <p>I know that for the classic Play framework it's <code>play debug ~run</code>. I tried running <code>activator debug ~run</code> but I get the following error:</p>
  
  <pre><code>[error] Not a valid command: debug (similar: idea)
  [error] Not a valid project ID: debug
  [error] Expected ':' (if selecting a configuration)
  [error] Not a valid key: debug (similar: debianSign, node)
  [error] debug
  [error]      ^
  </code></pre>
  
  <p>What am I doing wrong?</p>
