我使用GWT 2.9.0 + GXT 4.1.0 + Java 11组合。我得到了误差以下的值[ERROR]提示:您的源代码似乎不在名为'client'的子包下面;没问题，但是你需要在你的模块中使用这个指令来使它可访问ProjectName。下面是我在eclipse中的package explorer中的项目结构。当我试图通过eclipse IDE中的gwt eclipse插件在超级开发模式下运行应用程序时，我得到了错误。你能帮我解决这个问题吗?

你的。gwt.xml文件都位于/cname/project/目录下，并且只列出这些子包作为源代码:
<source path="client" /> <source path="service" /> ... <source path="model" /> <source path="service" /> <source path="util" />
(注意你有"服务"列出两次，两个.gwt.xml文件都声称服务器包是其自己模块的一部分)。
由于没有模块声明com.cname.proj的顶级包，该源文件在编译时将不可用。
期望的模式是只列出编译器期望将其所有内容转换为JS的包。通常，这是client子包，但惯例通常表明也可能存在shared子包，由服务器和客户端之间共享的代码组成。列出其他如service,model,util没有问题，技术上也可以只列出空字符串来指示整个当前包和所有子包:
<source path="" />
说了这么多，最好的选择是将Main移到com.cname.proj.client中，因为它几乎肯定是一个专门的客户端类。
