java - 如何让 Java FX 在 Ubuntu 18.04.2 LTS 上与 OpenJDK 8 一起运行？

Question

尝试在环境中编译 JavaFX 应用程序时:

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

我试图通过以下链接找到解决方案:

• https://mvnrepository.com/artifact/org.openjfx/javafx/11
• Maven project with JavaFX (with jar file in `lib`)
• https://github.com/javafx-maven-plugin/javafx-maven-plugin

• https://askubuntu.com/questions/609951/javafx-is-not-on-the-default-classpath-even-with-oracle-jdk-1-8
• Why is JavaFX is not included in OpenJDK 8 on Ubuntu Wily (15.10)?
• http://can4eve.bitplan.com/index.php/JavaFX

最有前途的行动去哪里

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

但错误仍然存​​在。

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

有帮助。命令:

apt purge openjfx
apt install openjfx=8u161-b12-1ubuntu2 libopenjfx-jni=8u161-b12-1ubuntu2 libopenjfx-java=8u161-b12-1ubuntu2
apt-mark hold openjfx libopenjfx-jni libopenjfx-java
