title: Version 1.8 of project facet java does not exist
body: <p>I'm trying to build a <code>Dynamic Web Application</code> in eclipse using Java 8 (and Wildfly appServer if that matters) but I'm unable to make Eclipse Luna M5 use Java 8 (I do have Java 8 BETA support installed and it works on JavaSE projects). </p>
  
  <p>In my POM I set the level to Java 8:</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt;
      &lt;version&gt;3.1&lt;/version&gt;
      &lt;configuration&gt;
          &lt;source&gt;1.8&lt;/source&gt;
          &lt;target&gt;1.8&lt;/target&gt;
      &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>But after I do <code>maven -&gt; update project</code> I get the following error:</p>
  
  <pre><code>Could not update project ExampleApp configuration
  Version 1.8 of project facet java does not exist.
  </code></pre>
  
  <p>And indeed there is no java 1.8 project facet under <code>project-&gt;preferences-&gt;project facets-&gt;java</code></p>
  
  <p>Can I manually create such <code>facet</code> and add It to to eclipse or I'll have to wait until java 8 is released and the eclipse guys decide to add it ?</p>
