Install OpenJDK 8 on Mac using brew (AdoptopenJDK)

In this tutorial, I will show you how to install OpenJDK 8 Mac. You have to pay for Oracle JDK so it’s better to use OpenJDK.

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.


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.

OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_202-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.202-b08, mixed mode)
