我正在使用带有 maven 插件的 gwt。我的web.xml样子是这样的：
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">
<!-- Servlets -->
<servlet>
<servlet-name>queryServiceImpl</servlet-name>
<servlet-class>com.vo.search.server.QueryServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>queryServiceImpl</servlet-name>
<url-pattern>/admin/queryService</url-pattern>
</servlet-mapping>
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>Admin.html</welcome-file>
</welcome-file-list>
</web-app>
我的模块Admin.gwt.xml看起来像这样：
<module rename-to='admin'>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name="com.google.gwt.core.Core" />
<inherits name='com.google.gwt.user.User' />
<inherits name="com.google.gwt.i18n.I18N" />
<inherits name="com.google.gwt.i18n.CldrLocales" />
<inherits name="com.google.gwt.user.theme.clean.CleanResources" />
<!-- Enable debug ID. -->
<inherits name="com.google.gwt.user.Debug" />
<set-property name="gwt.enableDebugId" value="true" />
<!-- We need the JUnit module in the main module, -->
<!-- otherwise eclipse complains (Google plugin bug?) -->
<!-- <inherits name='com.google.gwt.junit.JUnit' /> -->
<!-- Inherit the default GWT style sheet. You can change -->
<!-- the theme of your GWT application by uncommenting -->
<!-- any one of the following lines. -->
<inherits name='com.google.gwt.user.theme.clean.Clean' />
<!-- <inherits name='com.google.gwt.user.theme.standard.Standard'/> -->
<!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
<!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> -->
<!-- Other module inherits -->
<!-- Specify the app entry point class. -->
<entry-point class='com.vo.search.client.Admin' />
<!-- Specify the app entry point class. -->
<!-- Specify the paths for translatable code -->
<source path='client' />
<source path='shared' />
</module>
最后，我的pom.xml样子是这样的：

构建和运行项目工作正常。尝试访问我在控制台中看到的页面时：

我认为问题在于它admin.nocache.js在admindir 中查找文件，但生成的 dir 实际上是Admin即使我的rename-to属性admin在模块配置文件中。更改rename-to属性以匹配没有帮助。
这是我由gwt-maven-plugin archetype创建的项目组织：
