Install/Verify Java (Linux)
You will need Java installed if you want to:
- run the current version of the Fabric Installer
- use MultiMC
- change the default “JAVA EXECUTABLE” to other than the bundled Java runtime in a Minecraft Launcher “Installation”
STEP 1: Verify if Java is already installed
Open a terminal window and execute java -version
.
If it returns with something like this, Java is already installed.
saiko@invader ~ % java -version openjdk version "14.0.1-internal" 2020-04-14 OpenJDK Runtime Environment (build 14.0.1-internal+14-adhoc..jdk14u-jdk-14.0.17) OpenJDK 64-Bit Server VM (build 14.0.1-internal+14-adhoc..jdk14u-jdk-14.0.17, mixed mode, sharing)
STEP 2 Install Java
Install Java using your distribution's package manager. This step will vary across distros, so in case it is not listed here, please refer to your distro's documentation.
Arch Linux
Install the latest JRE with this command:
pacman -S jre-openjdk
If you're only running a server without the need for a graphical environment, the headless JRE is enough:
pacman -S jre-openjdk-headless
If you want to also develop mods, you need to install the JDK instead.
pacman -S jdk-openjdk
For more information, see the wiki article.
Fedora
Install the JRE for Java 8 with this command:
sudo dnf install java-1.8.0-openjdk
If you're only running a server without the need for a graphical environment, the headless JRE is enough:
sudo dnf install java-1.8.0-openjdk-headless
If you want to also develop mods, you need to install the JDK instead.
sudo dnf install java-1.8.0-openjdk-devel
For more information, see the wiki article.
Gentoo
Install the latest JRE with this command:
emerge jre
If you're only running a server without the need for a graphical environment, the headless JRE is enough, for that you can enable USE=headless-awt and then emerge a JRE that supports it, such as dev-java/openjdk or dev-java/openjdk-jre-bin for the precompiled version:
euse -E headless-awt # or manually change make.conf/package.use emerge jre
If you want to also develop mods, you need to install the JDK instead.
emerge jdk
For more information, see the wiki article.
Void Linux
Install the latest JRE with this command:
xbps-install openjdk-jre
If you want to also develop mods, you need to install the JDK instead.
xbps-install openjdk
