body: <p>I'm new to <code>npm</code>, <code>yo</code> and this mega hipster staff.
  I want to test the new branch 2.0, because I saw and error will trying the <a href="https://github.com/jhipster/jhipster-sample-app-2.0" rel="nofollow">jhipster-sample-app-2.0</a>. In concrete an anjular-ui-router javascript can not we loaded.</p>
