Question

我最近开始在Eclipse（m2eclipse）中使用Maven。不幸的是，最近我无法从Eclipse运行该应用程序。我收到错误：

加载模块src.main.java.com.ohapp.webconfuturo.WebConfuturo 加载继承模块'src.main.java.com.ohapp.webconfuturo.WebConfuturo' [错误]无法找到你的'src / main / java / com / ohapp / webconfuturo / WebConfuturo.gwt.xml' 类路径;可能是一个错字，或者你可能忘了包括一个类路径来源？ [错误] shell在doStartup方法中失败

我已经检查过，文件就在那里。在Eclipse中不可见但在文件系统中。

奇怪的是，如果我通过Maven（mvn gwt：run）运行该程序，它的工作正常。

我的pom.xml（没有依赖项）如下：

我做错了什么？

由于

Answer 1

我想出了这个。我的运行设置中的参数错误。我有使用完整路径引用的gwt.xml文件，而不是相对于源文件夹：

src.main.java.com.ohapp.appname.AppName

我把它改为：

com.ohapp.appname.AppName

问题解决了。

我不知道这是怎么发生的，因为不是我做出了改变。
