Question

我在 GWT 2.9.0 上运行我的应用

我完成了所有很好的 util 重建项目。

从今天起，我的 GWT 项目不再工作！

我从 Intellij Ultimate 运行它们

HTML 打开，但程序无法编译。

我收到这条消息：

现在我不知道该怎么办。我是 GWT 的新手。第一次接触时非常坚固的工具。

这是一些代码：我的 pom.xml:

我还没有在 sackoverflow 上找到任何解决我的问题的方法。

检查文件中的 GWT facet 是否正确配置 |项目结构 |模块 | | GWT 和Target Web Facet 已设置。

Web facet 还应该设置 Web Resources Directory 和 Source Roots。
