问题 无法通过延迟绑定解析类

// ...some imports

public class Menu {
    final MenuMaker myClass = GWT.create(MenuMaker.class);  // ERROR

我的... gwt.xml：

...
<generate-with class="com.gwt.rebind.MenuGenerator">
  <when-type-assignable class="com.gwt.client.MenuMaker" />
</generate-with>
...

当我在DevMode中运行编译但是当我“使用GWT编译器构建项目”时，所有工作都完美无缺，我收到此错误：

      [ERROR] Line 15:  Failed to resolve 'com.gwt.client.MenuMaker' via deferred binding
   Scanning for additional dependencies: jar:file:/C:/eclipse/plugins/com.google.gwt.eclipse.sdkbundle_2.4.0.v201208080121-rel-r42/gwt-2.4.0/gwt-user.jar!/com/google/gwt/dom/client/DOMImpl.java
      [WARN] For the following type(s), generated source was never committed (did you forget to call commit()?)
         [WARN] com.gwt.client.MenuMakerGen
   [ERROR] Cannot proceed due to previous errors

在com.gwt.rebind.MenuGenerator的末尾：

sourceWriter.commit(logger);

我需要帮助。
