Question

我试图用Visual Studio Code设置JavaFX。我引用了Jose Pereda的this很好的答案。但是，即使经过最后一步，也无法正常工作。它仍然显示：

这句话让我真正感到难过，我无法理解的是：

Caused by: java.lang.NoSuchMethodException: com.Main.<init>()

我的目录结构： Directory Structure

有人可以解释这意味着什么以及如何解决吗？

如果您还有其他需要，请回复。我不确定要放什么。

应用程序构造函数中的异常：由以下原因引起：java.lang.NoSuchMethodException：Main。<init>（）
