Keywords: Java, JDK (Java Development Kit), MacOS, Homebrew, Specific Version
This how-to guide covers how to install different versions of the JDK on MacOS with Homebrew.
This guide favors OpenJDK.
This guide favors free, simple, and permissive licensing whenever possible, so we will favor OpenJDK first, then AdoptOpenJDK if plain OpenJDK isn't available, any other open source distributions, and finally Oracle JDK if no other options are available. We favor OpenJDK because it has a permissive license, the GPL v2 with Classpath Exception (aka linking exception). For more information, see Oracle now requires a subscription to use Java SE (2018).
- For Java 8 and later, OpenJDK is readily available.
- For versions prior to Java 8 or other special circumstances, OpenJDK may not be available. We will cover how to install whatever is most readily available.
Note that this guide contains plenty of CLI command outputs. The intent of including these outputs is to illustrate what output should look like. Our goal IS NOT to keep up with exactly what the output is at the present day. This guide DOES NOT guarantee or even attempt to keep all those command outputs updated with the ever-evolving Hombrew formulae changes.
What's important are the commands, and the general form of the outputs. This guide WILL attempt to keep up-to-date with the best commands to run.
Just be aware that if something's been working for a while, the command output might look old, but the command itself will probably still run fine for more recent updates.
Install Homebrew.
Remember to frequently brew update. Homebrew may also auto-update upon running key homebrew commands such as install or upgrade.
$ brew update
Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/cask).
==> Updated Casks
fooDouble check your registered taps by running brew tap. It's generally good practice to have homebrew/cask and homebrew/cask-versions taprooms tapped, especially when installing multiple Java versions.
Check your taps.
$ brew tap
homebrew/cask
homebrew/cask-versions
homebrew/core
homebrew/servicesIf homebrew/cask and homebrew/cask-versions aren't in the list of your registered taps, then run brew tap homebrew/cask and brew tap homebrew/cask-versions to tap them.
Tap into the cask caskroom.

Tapped 166 casks (213 files, 65.6MB).A lot of the information in this how-to guide is simply gathered from brew search and brew info. If you're still getting the hang of things, I highly recommend you run these commands yourself to get an overview of what's available and learn how to search Homebrew's formulae.
Java/JDK formula/cask names typically contain either java or jdk. Let's brew search for java and jdk to see potential formulas.
$ brew search java
==> Formulae
app-engine-java java11 ✔ jslint4java
google-java-format javacc libreadline-java
java ✔ javarepl pdftk-java
==> Casks
charles-applejava eclipse-javascript java6 netbeans-java-se
eclipse-java java-beta netbeans-java-ee oracle-jdk-javadoc
If you meant "java" specifically:
It was migrated from homebrew/cask to homebrew/core.We can see some of the formulae/casks we're looking for, such as java, java11, or java-beta.
$ brew search jdk
==> Formulae
openjdk ✔ openjdk@11 ✔ openjdk@8 ✔
==> Casks
adoptopenjdk jdk-mission-control oracle-jdk-javadoc
adoptopenjdk8 oracle-jdk sapmachine-jdkWe can see some more potential formulae/casks we're looking for, such as openjdk, adoptopenjdk8, and oracle-jdk.
Get the summary and metadata for a formula/cask you are interested in by running brew info <formula> or brew cask info <cask>.
As an example, let's start simple and get the info of java. java is an alias for the openjdk formula. At the time of writing, the current version is OpenJDK 15.
$ brew info java
Warning: Treating java as a formula.

$ brew install openjdkNOTE: Pay attention to the caveat about manually symlinking the jdk into /Library/Java/JavaVirtualMachines. It's a manual "opt-in" to treating the Java installation as recognizable by the system at large. It's recommended you run the provided symlink command.
JDK 11 is an LTS (Long Term Support) version.
- There is no such thing as a
java-ltsformula or cask, because there is no single LTS version. You must explicitly choose to install Java 11. - Note that this formula is available on
homebrew/core, so you don't need to have tapped any caskrooms. - There is a
java11alias which points toopenjdk@11.
$ brew info openjdk@11 # Confirm information about the formula. Note that it's poured from the OpenJDK formula.
$ brew install openjdk@11 # Install OpenJDK 11Homebrew does not offer an obvious way to install an older feature release of Java other than the current generally-available feature release. For example, there is no such formula as openjdk@14 or java14 in homebrew/core, nor is there such a cask in homebrew/cask or homebrew-cask-versions.
There is good reason for this; out-of-date feature releases are explicitly not supported by OpenJDK. Only the current feature release is supported (thus we get formulae with continual version updates like openjdk). Quoting jdk.java.net - JDK 14 Releases:
JDK 14 has been superseded. Please visit jdk.java.net for the current version.
Older releases, which do not include the most up to date security vulnerability fixes and are no longer recommended for use in production, remain available in the OpenJDK Archive.
If you still need to install an Older JDK Feature Release, here are some recommendations.
-
Manually download and install your desired version from the OpenJDK Archive.
-
Use SDKMAN to install either OpenJDK or AdoptOpenJDK versions. See SDKMAN for more info.

Brew has an openjdk@8 formula.
$ brew info openjdk@8
$ brew install openjdk@8Another option is installing AdoptOpenJDK 8 via cask.
$ brew tap homebrew/cask-versions # cask-versions must be tapped to get access to this caskto different cask versions.
$ brew search jdk # Find `adoptopenjdk8` in the casks
$ brew cask info adoptopenjdk8 # Confirm information about the cask. Note that this is an AdoptOpenJDK build of OpenJDK.
$ brew cask install adoptopenjdk8 # Install the AdoptOpenJDK build of OpenJDK8See the AdoptOpenJDK HomeBrew Tap Github Repo for an alternative taproom with more AdoptOpenJDK versions.

# THIS IS OBSOLETE. INCLUDED FOR REFERENCE PURPOSES.
