GWT代码服务器未使用maven原型在新生成的项目中查找模块
我已经和GWT和eclipse合作了一段时间了，我想用maven和GWT插件（gwt-maven-plugin， 在这里输入链接描述 ）。 我试图在eclipse（Luna 4.4）中使用它，但显然我没有正确地做到这一点，因为它非常脆弱，因为当我改变了一些小的东西时，它会定期打破它的设置。 pom.xml。 所以我决定退后一步，消除eclipse的黑魔法，并从命令行从头开始一个新项目。
但是，我似乎无法掌握运行实际应用程序的问题，因为当我执行代码服务器时，导航到该页面，我看到以下消息：
Can't find any GWT Modules on this page. 显然，代码服务器正在运行，但模块文件似乎尚未托管。 AFAIK我看了几个小时的自学（并找到http://blog.ltgt.net/how-does-gwts-super-dev-mode-work/ ），应该有第二个进程实际并行托管代码到代码服务器。 用maven做这个的合适方法是什么？ 我应该打开第二个终端并与代码服务器并行运行docker或其他东西吗？ 如果是这样，有人可以给我一个提示，告诉我如何最有效地做到这一点？
提前致谢！
以下是我创建项目的方法：

使用GWT 2.7+，您只需要启动mvn gwt:run ，它将在封面下使用SuperDevMode，“重新编译加载”（而不是使用bookmarklet）。
请注意， gwt:run不会复制您的src/main/webapp或您的依赖项，因此您可能必须运行mvn war:exploded （或mvn package ）作为先决条件（并且每次更改src/main/webapp的文件时） src/main/webapp或者你需要刷新你的依赖项）
话虽这么说，除非您的项目非常简单，否则您应该尽早开始使用不同的Maven模块来获取客户端和服务器代码; 这是因为Maven坚持认为你不能在同一个POM中管理“GWT客户端类路径”和“服务器端类路径”。
我发布了原型以帮助设置所有内容： https ： //github.com/tbroyer/gwt-maven-archetypes （遗憾的是我还没有时间将它们更新为GWT 2.7）
无论是那个还是使用Gradle ……
