java - 删除示例包仍然出现编译错误

Question

我正在JavaFX中创建一个项目，当我创建一个新项目时，它给了我一个名为sample的包。我决定不使用包装，将所有类剪切并粘贴到 src 包中，并制作我的 fxml 文件。我收到一个错误，看起来好像 java 正在寻找示例包，但我删除了它。我在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？

您的项目配置似乎存在一些问题。因此，在 IDEA 中尝试:“运行”->“编辑配置”并检查您的设置。

如果左侧部分没有任何类名称(例如我的 MainSTE、MainSCI) - 只需添加它:“+”->“Application”，然后指定类名称(屏幕截图中带下划线的按​​钮)
