问题描述
我设法打破了旧 MacBook 并换了一台新的。重新安装 IntelliJ 并从 Git 检索 Kotlin TornafoFX 项目后,IDE 不再识别任何 JavaFX 组件。我将 JavaFX 添加到 POM,现在看起来像这样:
<?xml version="1.0" encoding="UTF-8"?>

我也收到 IDE 报告的类似错误:
java.lang.NoClassDefFoundError: javafx/scene/paint/Color
这在我的旧机器上没有发生,而且 POM 中甚至不需要 JavaFX。有人可以帮我吗?
解决方法
结果我不得不恢复到 JDK1.8。不会问为什么...
