We cannot use Oracle Java for modern versions of Java, since they have commercial usage restrictions which mean some users (particularly, those making money off of Minecraft) would have to pay to use it.įortunately, we can use OpenJDK, which is identical to Oracle Java but does not have the same restrictions. Java comes in many shapes and forms, which may make it confusing exactly which version of it you should have installed, which is what this should hopefully explain. “Minecraft Java Edition” is named as such because it is written in Java. The source code of the Java Platform, Standard Edition 11 Reference Implementations binaries is available under the GPLv2 in a single zip file.The Java Runtime Environment (JRE) is software that allows for programs written in the Java programming language to run on your computer. Open a new terminal and verify: echo $JAVA_HOME In ~/.zshenv, I set the variable like so: export JAVA_HOME=$(/usr/libexec/java_home) Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed.

JAVA_HOME is an important environment variable and it’s important to get it right. … hopefully showing something like this: openjdk 19.0.1 After opening a terminal, the successful installation of the JDK can be confirmed like so: java -version Library/Java/JavaVirtualMachines/temurin-19.jdk/Īlmost done. Like you can see, the package installer will put the JDK into this location:

Otherwise, the easiest way is to select macOS 圆4 and OpenJDK 19, download and install the pkg file.

If you are already using Homebrew then the easiest way to get the JDK on to your Mac might be this: $brew install -cask temurin All available versions for supported platforms can be found here. As I’m writing this, Java 19.0.1 is the latest version and Adoptium is one of the best places to find Prebuilt OpenJDK Binaries.Īdoptium was known as AdoptOpenJDK, before the project was moved to the Eclipse Foundation. For some time now, Java is not (pre-)installed anymore, let’s fix that.
