如何在Ubuntu 18.04.2 LTS上使Java FX与OpenJDK 8一起运行? [英] How do I get Java FX running with OpenJDK 8 on Ubuntu 18.04.2 LTS?

问题描述

在环境中尝试编译JavaFX应用程序时:

When trying to compile an JavaFX application in the environment:

java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b03-0ubuntu1.18.04.1-b03)
OpenJDK 64-Bit Server VM (build 25.212-b03, mixed mode)

cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"

我收到错误消息:

cannot access javafx.event.EventHandler
[ERROR]   class file for javafx.event.EventHandler not found

最有前途的行动

1. 使用apt安装openjfx来安装openjfx
2. 将JAVA_HOME环境变量设置为/usr/lib/jvm/java-8-openjdk-amd64

但是错误仍然存​​在.

But the error persists.

要使OpenJDK 8和JavaFX在Ubuntu 18.04.2 LTS上运行需要做什么?
