OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).^[1] It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) version 2 with a linking exception. Were it not for the GPL linking exception, components that linked to the Java class library would be subject to the terms of the GPL license.

Requirements

brew should be installed (https://brew.sh/)

1. Brew tap

First of all, we need to tap a brew repo. Execute the following command:

$ brew tap AdoptOpenJDK/openjdk

The above will add more repositories to brew.

2. Install OpenJDK 8 Mac

After adding tap, let’s install OpenJDK using brew.

$ brew cask install adoptopenjdk8

Or on newer Mac OS Version
$ brew install --cask adoptopenjdk8

So, now we have installed Java 8, we can check installation with the following command.

3. Check JDK Version

Now we can check the JDK version.

# java -version openjdk version "1.8.0_202" OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_202-b08) OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.202-b08, mixed mode)

Now Java has installed properly.

4. Java Location

Now let’s check the java path.

# which java /usr/bin/java

Hi, good tutorial thanks. It simply miss information about ‘java_home’. Have found it using cmd “/usr/libexec/java_home -V”

Thanks for the article, had to change step 2 to “brew install –crew adoptopenjdk8” to make it work on MAC Catalina.
