自JDK 8起，我就使用JavaFX来开发具有出色UI组件的桌面应用程序。最近，我将JDK版本13下载到我的intellij IDEA，并开始通过Scene Builder应用程序开发一个小程序。我首先设置了场景构建器的路径，并创建了一个JavaFX项目，但是它不起作用。当我按下播放按钮时，显示以下错误
Error:(21, 9) java: cannot find symbol
symbol: method launch(java.lang.String[])

Error:(5, 20) java: package javafx.scene does not exist
Error:(3, 26) java: package javafx.application does not exist
Error:(4, 19) java: package javafx.fxml does not exist
为什么会这样， 我应该怎么做才能摆脱这些错误，并像以前在JDK 8中那样开发应用程序， JavaFX是否可以替代以创建基于UI的应用程序。
