Ubuntu – JavaFX missing, Ubuntu 18.04


I have Java 8 and Ubuntu 18.04. I'm using NetBeans and when tried to make some program, it couldn't be done because JavaFX is missing.

I installed Java JDK with NetBeans from Oracle's site and thought everything is included but obviously I didn't check it well.

What should I do, what should I install? I'm not so good at this and don't know if problem is with Ubuntu or Java. 🙁

In the Ubuntu 16.04 and later default repositories JavaFX is packaged as a separate package named openjfx. To install it in Ubuntu 18.04, open the terminal and type:

sudo apt install openjdk-8-jdk openjfx

Check that JDK 8 is selected as the default Java version in Netbeans -> Tools -> Options -> Java -> Nashorn tab -> click the Manage Platforms button -> click the Add Platform button -> click the radio button marked Java Standard Edition -> click the Next button -> browse to /usr/lib/jvm/java-8-openjdk-amd64 and select it as the default Java version.

Optionally you can install openjdk-11-jdk instead of or alongside openjdk-8-jdk. openjfx works with both openjdk-8-jdk and openjdk-11-jdk in Netbeans in Ubuntu 18.04. I am using Netbeans 8.2 10.0 in Ubuntu 18.04.
