OpenJFX N is formally compatible with JDK N and N-1. For OpenJFX 13, download OpenJDK 12 or later to use as the boot JDK to build and test OpenJFX. We recommend JDK 13to use the latest version, however, only Gradle 6 supports Java 13 and it is not released yet, so use JDK 12Gradle might not support that version, so a version that Gradle supports might also be required to run Gradle itself (though it will use the latest version of the JDK through toolchain support).

Git

OpenJFX (and OpenJDK) transitioned to Git as part of Project Skara. The OpenJFX repo is hosted on GitHub at openjdk/jfx. We encourage developers to become familiar with Git and GitHub.

Gradle is the primary build tool for building OpenJFX. Since the repository includes a Gradle wrapper that will download the correct Gradle version when needed, you do not need to manually install Gradle. The current and minimum Gradle versions are defined in the source code. If you want to generate a wrapper yourself (for example, you want to build OpenJFX with a different Gradle version), then you will need to install Gradle.
