title: "Module has no entry points defined", except it does (migrating the gwt-maven-plugin)
body: <p><code>[INFO]    [ERROR] Module has no entry points defined</code></p>
  <p>I am migrating from org.codehaus.mojo:gwt-maven-plugin to net.ltgt.gwt.maven:gwt-maven-plugin, and I can't seem to convince the compiler that my module DOES have an entry point defined.</p>
  <p>The old plugin could only work with older Java, which I don't have anymore... So I moved on to the newer incarnation of the GWT Maven plugin... Unfortunately this plugin uses parameters that GWT 2.0.2 compiler does not recognize (like -deploy or -sourceLevel)... Which forced me to change ${gwt.version} to 2.8.2. That's rather massive jump, but I don't see how that could invalidate something as simple as implementing the EntryPoint interface.</p>
  <p>TheApp/Web/src/main/module.xml:</p>
  <pre><code>    &lt;entry-point class='net.theapp.client.TheEntryPoint' /&gt;
  ...
      &lt;source path='net/theapp/client'/&gt;
      &lt;source path='net/theapp/data'/&gt;
  </code></pre>
  <p>Location of the entry-point class:</p>
  <pre><code>TheApp/Web/src/main/java/net/theapp/client/
    - TheEntryPoint.java
  </code></pre>
  <p>The class:</p>
  <pre><code>...
  public class TheEntryPoint
      implements EntryPoint
  {
  ...
  </code></pre>
