我的GWT应用程序目前使用maven打包成战争，然后将其部署到tomcat。我想更改为jar中的包装，以便可以使用java -jar执行，并使应用程序从Jetty等嵌入式Web服务器提供。类似于在开发模式下运行时发生的情况，但我希望它来自一个易于部署的胖/超级jar包括html和GWT js文件。我只能找到使用spring为Jetty执行此操作的说明，并且无法使其适应GWT。像Jetty's example uber jar project这样的东西很接近，只需要和GWT一起工作。

您只需更改maven项目的包装即可：
<project>
...
<packaging>jar</packaging>
...
</project>
请注意couldnt deploy a jar file in tomcat。
接下来，我将确保依赖项gwt-dev已提供范围（因为此依赖项已包含旧版本的jetty）。之后，您可以添加jersey依赖项并启动一个为您的GWT-Appliccation提供服务的嵌入式服务器（例如see here）。

结合example Jetty project和@ mam10eks的答案，我想我还是设法找到了一个简单的GWT应用程序：
的pom.xml：
