      Description

      ADDITIONAL SYSTEM INFORMATION :
      OS: Ubuntu 20.04 LTS (64 bit)
      JDK:
      OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1ubuntu1-b09
      OpenJDK 64-Bit server VM (build 25.252-b09, mixed mode)
      Attempted openJFX mercurial revision: 10300

      A DESCRIPTION OF THE PROBLEM :
      There are no instructions for compiling openJFX 8 on any ubuntu platforms after 16. I attempted to build it via the instructions for 14-16, but was unsuccessful.

      Building for newer versions of Ubuntu is critical because there no longer exists (as far as I can find) and openjfx 8 packages for ubuntu, so the only way to install it would be to build it from source. (See https://bugs.launchpad.net/ubuntu/+source/openjfx/+bug/1799946 which had a workaround solution which worked until recently when version 8u161-b12-1ubuntu2 was removed). There are still many applications out there which do not support Java 9+, so this capability is a necessity.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      On fresh Ubuntu 20.4 VM:
      apt -y update && apt -y install openjdk-8-jdk unzip
      export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
      apt -y install ksh bison flex gperf libasound2-dev libgl1-mesa-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libjpeg-dev libpng-dev libx11-dev libxml2-dev libxslt1-dev libxt-dev libxxf86vm-dev pkg-config x11proto-core-dev x11proto-xf86vidmode-dev libavcodec-dev mercurial libgtk2.0-dev libgtk-3-dev libxtst-dev libudev-dev libavformat-dev
      apt -y install cmake ruby
      wget https://services.gradle.org/distributions/gradle-5.0-bin.zip -P /tmp
      unzip -d /opt/gradle /tmp/gradle-*.zip
      export GRADLE_HOME=/opt/gradle/gradle-5.0
      export PATH=${GRADLE_HOME}/bin:${PATH}
      hg clone https://hg.openjdk.java.net/openjfx/8u-dev/rt
      cd rt
      gradle --scan


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Compile open JFX
      ACTUAL -
      gradle --scan
