我編譯在Eclipse中我的GWT模塊繼承我的其他模塊（即編譯沒有問題），我得到這樣的輸出：GWT編譯問題的構造函數的StackTraceElement（字符串，字符串，字符串，整數）是未定義

我的模塊定義是：
<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>
如何解決這類問題彙編的？我忘了從其他模塊繼承（我嘗試添加那些類未解決，即使它們應該通過用戶模塊繼承，並沒有幫助）？我的Eclipse項目設置中是否有任何缺失（mymodule位於單獨的項目中，配置了GWT，gwt 2.0.4，其他模塊和JAR是否在項目依賴項中設置）？
