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. OpenJDK 64-Bit Server VM Temurin-17.0.3+7 (build 17.0.3+7, mixed mode, sharing) OpenJDK Runtime Environment Temurin-17.0.3+7 (build 17.0.3+7) … hopefully showing something like this: openjdk 17.0.3 After opening a terminal, the successful installation of the JDK can be confirmed like so: java -version Library/Java/JavaVirtualMachines/temurin-17.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 17 (LTS), 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 17.0.3 is the latest LTS (Long Term Support) 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. % /usr/libexec/java_home -v 1.8.0_06 -exec javac -versionįor more information, see the java_home(1) man page.For some time now, Java is not (pre-)installed anymore, let’s fix that. To run a different version of Java, either specify the full path, or use the java_home tool: Java HotSpot(TM) 64-Bit Server VM (build 23.2-b04, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_06-ea-b13) If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. You can determine which version of the JDK is the default by typing java -version in a Terminal window. It is possible for the version of the JRE to be different than the version of the JDK. When launching a Java application through the command line, the system uses the default JDK. There can be multiple JDKs installed on a system, as many as you wish. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'. If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. Determining the Default Version of the JDK
