title: Where is complete() defined in Jake tasks?
body: <p>My editor is complaining that <code>complete()</code> is undefined in a <code>task</code>.</p>
  
  <p>Where is it defined? Can I do something like this?</p>
  
  <pre><code>const { task, exec } = require('jake')
  task('default', () =&gt; {
    exec(..., () =&gt; this.complete())
  })
  </code></pre>
