If the major version of the available JDK is unique you can just use the major version, like: export JAVA_HOME=`/usr/libexec/java_home -v 1. Java will be installed here: /usr/local/opt/openjdk17/bin/java For the system Java wrappers to find this JDK, symlink it with: sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk. For example, I will choose the 1.8.0_121 version to be my default JDK. Matching Java Virtual Machines (3):ĩ, x86_64: 'Java SE 9' /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Homeġ.8.0_121, x86_64: 'Java SE 8' /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Homeġ.7.0_80, x86_64: 'Java SE 7' /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Homeįrom the list above pick which version you want to be the default JDK.

JAVAHOME is essentially the full path of the directory that contains a sub-directory named bin which in turn contains the java. In this post you will learn how to set the default JAVA_HOME in Mac OS X when you have more than one JDK installed in your computer.
