Recommended versions of Java
We recommend installing a full Java JDK, while Mango should work with just a JRE we sometimes depend on tools only available in the JDK for our scripts and for providing support.
- Mango versions 4.0.x and higher require JDK 11.
Installing OpenJDK 11 on Debian/Ubuntu operating systems
You can easily install OpenJDK on Debian/Ubuntu by running
sudo apt update
sudo apt install openjdk-11-jdk-headless
Installing OpenJDK 11
OpenJDK is a free and open source version of the Java JDK. AdoptOpenJDK provides pre-built OpenJDK binaries for a variety of operating systems and architectures.
- Visit Adopt Open JDK.
- Select OpenJDK 11.
- Select HotSpot JVM.
- Choose your operating system and architecture.
- Download the archive or installer (for Windows or Mac). If you download the installer see the installation for further instructions.
- Extract the archive to your chosen location on your filesystem (e.g. /opt/openjdk).
- Set the JAVA_HOME environment variable to point to your installation directory.
- You may also want to add the bin directory to your path by appending $JAVA_HOME/bin to your PATH environment variable.
Setting your JAVA_HOME environment variable
Linux
Edit your /etc/environment file and add a line like JAVA_HOME=/opt/openjdk (Press Ctrl-X to exit, it will prompt to save).
