Question

我正在Eclipse中编译我的GWT模块，它继承了我的另一个模块（编译没有问题），我得到了这个输出：

Compiling module mymodule.GWT_TESTS

我的模块定义是：

<module>
    <inherits name='com.google.gwt.user.User'/>
    <inherits name="com.google.gwt.i18n.I18N"/>
    <inherits name='othermodule.Main' />

    <entry-point class='mymodule.client.GWT_TESTS'/>
</module>

如何解决这种编译问题？我是否忘记继承其他模块（我试图添加那些类没有解决的，即使它们应该通过用户模块继承而且它没有帮助）？我的Eclipse项目设置中是否有任何我缺少的东西（mymodule在一个单独的项目中，GWT配置，gwt 2.0.4，其他模块和JAR是在项目依赖项中设置的）？

Answer 1

我删除了项目并再次重新创建它现在可以正常工作了。我最初使用Eclipse插件（2.3.0）附带的GWT，但后来我不得不将GWT版本更改为2.0.4。当我解决问题时，更改现有项目的GWT版本或我的其他更改都会导致错误。
