已删除的示例包仍出现编译错误

Question

我在JavaFX中创建了一个项目，当我创建一个新项目时，它为我提供了一个名为sample的包。我决定不使用这个包，将我所有的类剪切并粘贴到src包中，并创建了我的fxml文件。我得到了一个错误，看起来像是java正在寻找一个示例包，但我删除了它。我在我的代码中找不到任何显示任何地方引用的示例的内容。有什么想法吗？

似乎您在项目配置方面遇到了一些问题。因此，在IDEA中尝试：“运行”-> "EditConfiguration“并检查您的设置。

​

如果你在左边没有任何类名(像我的应用程序，MainSCI) -只需添加它："+“->”应用程序“，并指定类名(我的屏幕截图上带下划线的按钮)
