title: Verification task in gradle
body: <p>While I was reading the <a href="http://www.gradle.org/docs/current/userguide/java_plugin.html" rel="nofollow">gradle documentation 23.3</a> I faced with the verification task concept in the following context:</p>
  
  <blockquote>
    <p>Performs all verification tasks in the project.</p>
  </blockquote>
  
  <p>Couldn't you explain what it means?</p>
