title: Not a valid command: it when executing sbt it
body: <p>I followed the steps for adding integration tests found at <a href="http://www.scala-sbt.org/release/docs/Detailed-Topics/Testing#integration-tests" rel="nofollow">http://www.scala-sbt.org/release/docs/Detailed-Topics/Testing#integration-tests</a>.</p>
  
  <p>However, when I run <code>sbt it</code>, see the following:</p>
  
  <pre><code>$ sbt it
  [info] Loading project definition from myproj/project
  [info] Set current project to myproj (in build file:myproj/)
  [error] Not a valid command: it
  [error] Not a valid project ID: it
  [error] Expected ':' (if selecting a configuration)
  [error] Not a valid key: it
  [error] it
  [error]   ^
  </code></pre>
  
  <p><code>sbt test</code> works as expected</p>
