Install OpenJDK Versions 8, 9, and 10

brew tap AdoptOpenJDK/openjdk


brew search /adoptopenjdk/

The Formulae section contains the identifiers for the various JDK versions.

To install a specific JDK version: brew install <identifier>

e.g. to install OpenJDK 8: brew install adoptopenjdk/openjdk/adoptopenjdk-openjdk8

JAVA_HOME should be set by the developer to /usr/local/Cellar/adoptopenjdk-openjdk8/jdk8u172-b11.

Install OpenJDK Version 11

brew cask install adoptopenjdk

JAVA_HOME should be set by the developer to /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk.

If you download the .tar.gz for OpenJDK 11 directly from http://jdk.java.net/11/, there’s no obvious installation instructions (at least that I could find) on the OpenJDK website or in the .gz file. If you’ve done any fiddling with different JDK versions on MacOS before, you’ve probably come across the ‘/usr/libexec/java_home’ utility, which composes a number of useful things relating to the JDK that you’re currently using in your PATH. Click here for my previous article about this utility and answers to this StackOverflow post, which includes one of the most extensive and useful guides to running different JDK versions on MacOS that I’ve seen.

/usr/libexec/java_home: This will show you where the current JDK home is, for example:

/usr/libexec/java_home -V: This lists all installed JDKs, which is shown below:

To switch between JDKs, use /usr/libexec/java_home -v version (e.g. 10):


Knowing that your available JDKs are installed to /Library/Java/JavaVirtualMachines/ by default, moving the contents of the downloaded OpenJDK 11 dir from inside the .gz file to the same location would make sense.

Once you’ve moved it there, java_home -V now shows the new JDK in place:

Updating my aliases to quickly switch versions in my .bash_profile, I now have:


Sourcing the .bash_profile (source .bash_profile) and then running each alias, now I’ve got OpenJDK 11 set up and ready to go!
