title: What wtpversion value to use?
body: <p>In one article I have seen this instruction to convert a Maven project to a dynamic web Eclipse project:</p>
  
  <pre><code>mvn eclipse:eclipse -Dwtpversion=1.5
  </code></pre>
  
  <p>So, what does it mean <strong>wtpversion</strong> and its value <strong>1.5</strong>? What wtpversion value should I use with Eclipse Indigo and jdk 1.7.0?</p>
