title: "webxml attribute is required" error in Maven
body: <p>I am getting the following error: </p>
  
  <blockquote>
    <p>Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode)</p>
  </blockquote>
  
  <p>I have got <code>web.xml</code> in right place which is <code>projectname\src\main\webapp\WEB-INF\web.xml</code></p>
