title: Can't Run html libgdx with libgdx-utils
body: <p>Im trying to compile my libgdx game, its working for android and desktop, but not HTML GWT.</p>
  
  <p>Im using Intellij / Gradle for the project.</p>
  
  <p>I just added the <code>libgdx-utils</code> extension lib found here which seems to be causing the error: <a href="https://bitbucket.org/dermetfan/libgdx-utils/wiki/Dependency%20Instructions" rel="nofollow">https://bitbucket.org/dermetfan/libgdx-utils/wiki/Dependency%20Instructions</a></p>
  
  <p>The error i get when attempting this gradle command <code>./gradlew html:dist</code> is:</p>
  
  <pre><code>:html:compileGwt

  <p>Ive made some progress</p>
  
  <p>In my <code>GdxDefinition.gwt.xml</code> file i needed to add some <code>&lt;inheritis&gt;</code> tags:</p>
  
  <pre><code>&lt;inherits name='libgdx-utils' /&gt;
  &lt;inherits name='libgdx-utils-box2d' /&gt;
  </code></pre>
  
  <p>That error is now fixed but now i have about 10000 more errors that are similar</p>
