title: Export WAR missing on STS 4.12
body: <p>yesterday I updated my STS to the latest version 4.12.0 and today when I wanted to export my project to a .war file, this feature was not there anymore.</p>

  <p>Here you can see how it looked on my previous 4.8 version:

  <p>I read this issue: <a href="https://github.com/spring-projects/sts4/issues/53" rel="nofollow noreferrer">https://github.com/spring-projects/sts4/issues/53</a>
  As I do not use maven (our project exists since 2008 and back then we did not use it) I have no way to build a war file anymore or just go back to the previous version... I don't get it, why such an easy way to build war files has been removed?</p>
  <p>Any tipps on how I can solve this?</p>
