我的GWT應用程序目前使用maven打包成一場戰爭，然後部署到tomcat。我想更改爲使用jar包進行打包，以便可以使用java -jar執行，並通過嵌入式Web服務器（如Jetty）提供應用程序。與在開發模式下運行時發生的情況類似，但我希望它從包含html和GWT js文件的單個易於部署的fat/uber jar發生。我只能在春季爲Jetty找到這樣的說明，而且還沒有能夠適應GWT。像Jetty's example uber jar project這樣的東西很接近，只需要與GWT一起工作。如何使用maven將GWT應用程序打包在胖JAR中？
您可以簡單地改變你的Maven項目的包裝：
<project>
...
<packaging>jar</packaging>
...
</project>
請注意，您couldnt deploy a jar file in tomcat。
接下來我會確保依賴關係gwt-dev提供了作用域（因爲這個依賴包含已經舊版本的jetty）。之後，您可以添加運動衫依賴項並啓動一個嵌入式服務器，該服務器爲您的GWT應用程序提供服務（例如see here）。
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.project</groupId>
<artifactId>core</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
</project>
感謝您的回答，但這並不包括我問過的所有東西，即GWT編譯jar，嵌入式web服務器等js文件。 –
結合example Jetty project和@ mam10eks答案，我想我已經成功反正弄明白一個簡單的GWT應用程序：
的pom.xml：

主要方法：
Server server = new Server(8080);
URL webRootLocation = this.getClass().getResource("/app.html");
if (webRootLocation == null)
{
throw new IllegalStateException("Unable to determine webroot URL location");
}
URI webRootUri = URI.create(webRootLocation.toURI().toASCIIString().replaceFirst("/app.html$","/"));
WebAppContext altHandler = new WebAppContext();
altHandler.setResourceBase(Resource.newResource(webRootUri).toString());
altHandler.setDescriptor(Resource.newResource(webRootUri).toString() + "WEB-INF/web.xml");
altHandler.setContextPath("/");
altHandler.setParentLoaderPriority(true);
server.setHandler(altHandler);
server.start();
server.join();
}
剛發現雖然這與mvn package && java -jar一起工作，但它不起作用超級開發模式通過mvn gwt：run –
謝謝我已經嘗試了鏈接，它幫助我靠得更近，但是我仍然無法使用maven一切工作，並且我在解決方法之後可以獲得胖子jar即一切需要在罐子裏運行webapp，包括html，GWT js文件等，而不需要單獨的war文件。 –
