此消息的原因是您有一个 *。gwt.xml c $ c>< inherits name =com.google.gwt.junit.JUnit/> 。没有理由直接包含该模块，当您运行 GWTTestCase 时会自动添加。

The reason for this message is that you have a *.gwt.xml that <inherits name="com.google.gwt.junit.JUnit" />. There's no reason to ever include that module directly, it'll be automatically added when you run your GWTTestCases.

gwt-maven-plugin原型已知包括这样一个模块虽然（这是我不鼓励使用原型的许多原因之一）。

The gwt-maven-plugin archetype is known to include such a module though (one of the many reasons I discourage using that archetype).

删除违规<继承> ，然后重试（并且不要将建议的servlet添加到web.xml中）。

Remove the offending <inherits> and try again (and don't add the suggested servlet to your web.xml).
