Question

我一直在使用e（fx）clipse跟踪javafx的教程，我无法启动这个。我的代码与它们的代码完全相同，如果我使用Netbeans它可以工作，但是我在eclipse中遇到这个错误：

任何人都有任何解决方案可以让它与eclipse一起使用吗？

Answer 1

好吧我弄明白我做错了什么。 Netbeans会自动创建一个名为您的项目名称的包，所以当我添加控制器fxmlexample.FXMLExampleController时，它正在查找包fxmlexample，我刚刚使用默认包。

只需创建一个名为fxmlexample的包并将我的文件移到那里就可以修复它。

Javafx教程4将无法编译
