Alternatively will can use SDKMAN! which is a package manager for Gradle, Java, and many other frameworks on Ubuntu.

Following the SDKMAN! install instructions:

curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"

Before starting, a useful command to remember is "list" which shows all available versions:

sdk list java

Now install JavaFX and (optionally) Gradle using two easy commands:

sdk install java 8.0.322.fx-zulu
sdk install gradle 7.4.2

Note, the JDK will be installed in a hidden folder located at:

~/.sdkman/candidates/java/8.0.332.fx-zulu

Jetbrains Runtime

The Jetbrains runtime (customized JDK) is an option for installing on Linux. It provides font rendering fixes. Read more here.

Note: JDKs are also available from https://adoptopenjdk.net/, but they won't provide JavaFX, which breaks most of IHMC's robotics software.

Mac OS X

Download JDK and JavaFX from https://adoptopenjdk.net/ or https://www.azul.com/downloads/zulu/zulufx/
