Question or issue on macOS:

I want to install OpenJDK Java on Mac OSX and have it work alongside other JDK’s since it is a newer release. Currently, I downloaded the tar.gz and placed it in my path but that is hard to maintain.

Download Java 1.8.0_181 Jdk

The only other install I found that do more things automatically is the install via Homebrew cask. It looks like only the current version too:

Shows:

So I can install it from there, but then what? Am I stuck only with the new version?

How to solve this problem?

Solution no. 1:

Note:These solutions work for various versions of Java including Java 8, Java 11, and the new Java 15, and for any other previous Java version covered by the listed version managers. This includes alternative JDK’s from OpenJDK, Oracle, IBM, Azul, Amazon Correto, Graal and more. Easily work with Java 7, Java 8, Java 9, Java 10, Java 11, Java 12, Java 13, Java 14, and Java 15!

You have a few options for how to do the installation as well as manage JDK switching. Installation can be done by Homebrew, SDKMAN, Jabba, or a manual install. Switching can be done by JEnv, SDKMAN, Jabba, or manually by setting JAVA_HOME. All of these are described below.

Installation

First, install Java using whatever method you prefer including Homebrew, SDKMAN or a manual install of the tar.gz file. The advantage of a manual install is that the location of the JDK can be placed in a standardized location for Mac OSX. Otherwise, there are easier options such as SDKMAN that also will install other important and common tools for the JVM.

Installing and Switching versions with SDKMAN

SDKMAN is a bit different and handles both the install and the switching. SDKMAN also places the installed JDK’s into its own directory tree, which is typically ~/.sdkman/candidates/java. SDKMAN allows setting a global default version, and a version specific to the current shell.

Install SDKMAN from https://sdkman.io/install
List the Java versions available to make sure you know the version ID
Install one of those versions, for example, Java 15:
Make 15 the default version:
Or switch to 15 for the session:

When you list available versions for installation using the list command, you will see a wide variety of distributions of Java:

And install additional versions, such as JDK 8:

SDKMAN can work with previously installed existing versions. Just do a local install giving your own version label and the location of the JDK:

And use it freely:

More information is available in the SDKMAN Usage Guide along with other SDK’s it can install and manage.

SDKMAN will automatically manage your PATH and JAVA_HOME for you as you change versions.

Install manually from OpenJDK download page:

Download OpenJDK for Mac OSX from http://jdk.java.net/ (for example Java 15)
Unarchive the OpenJDK tar, and place the resulting folder (i.e. jdk-15.jdk) into your /Library/Java/JavaVirtualMachines/ folder since this is the standard and expected location of JDK installs. You can also install anywhere you want in reality.

Install with Homebrew

The version of Java available in Homebrew Cask previous to October 3, 2018 was indeed the Oracle JVM. Now, however, it has now been updated to OpenJDK. Be sure to update Homebrew and then you will see the lastest version available for install.

install Homebrew if you haven’t already. Make sure it is updated:
Add the casks tap, if you want to use the AdoptOpenJDK versions (which tend to be more current):
These casks change their Java versions often, and there might be other taps out there with additional Java versions.
Look for installable versions:
or for AdoptOpenJDK versions:
Check the details on the version that will be installed:
or for the AdoptOpenJDK version:
Install a specific version of the JDK such as java11, adoptopenjdk8, or adoptopenjdk13, or just java or adoptopenjdk for the most current of that distribution. For example:

And these will be installed into /Library/Java/JavaVirtualMachines/ which is the traditional location expected on Mac OSX.

Other installation options:

Some other flavours of OpenJDK are:

Azul Systems Java Zulu certified builds of OpenJDK can be installed by following the instructions on their site.

Zulu® is a certified build of OpenJDK that is fully compliant with the Java SE standard. Zulu is 100% open source and freely downloadable. Now Java developers, system administrators, and end-users can enjoy the full benefits of open source Java with deployment flexibility and control over upgrade timing.

Amazon Correto OpenJDK builds have an easy to use an installation package for Java 8 or Java 11, and installs to the standard /Library/Java/JavaVirtualMachines/ directory on Mac OSX.

Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK). Corretto comes with long-term support that will include performance enhancements and security fixes. Amazon runs Corretto internally on thousands of production services and Corretto is certified as compatible with the Java SE standard. With Corretto, you can develop and run Java applications on popular operating systems, including Linux, Windows, and macOS.

Where is my JDK?!?!

To find locations of previously installed Java JDK’s installed at the default system locations, use:

Matching Java Virtual Machines (8):
15, x86_64: “OpenJDK 15” /Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home
14, x86_64: “OpenJDK 14” /Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home
13, x86_64: “OpenJDK 13” /Library/Java/JavaVirtualMachines/openjdk-13.jdk/Contents/Home
12, x86_64: “OpenJDK 12” /Library/Java/JavaVirtualMachines/jdk-12.jdk/Contents/Home
11, x86_64: “Java SE 11” /Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home
10.0.2, x86_64: “Java SE 10.0.2” /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home
9, x86_64: “Java SE 9” /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
1.8.0_144, x86_64: “Java SE 8” /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home

You can also report just the location of a specific Java version using -v. For example for Java 15:

/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home

Knowing the location of the installed JDK’s is also useful when using tools like JEnv, or adding a local install to SDKMAN, or linking a system JDK in Jabba — and you need to know where to find them.

If you need to find JDK’s installed by other tools, check these locations:

SDKMAN installs to ~/.sdkman/candidates/java/
Jabba installs to ~/.jabba/jdk

Switching versions manually

The Java executable is a wrapper that will use whatever JDK is configured in JAVA_HOME, so you can change that to also change which JDK is in use.

For example, if you installed or untar’d JDK 15 to /Library/Java/JavaVirtualMachines/jdk-15.jdk if it is the highest version number it should already be t
