The goal of this post is to show that we could do just that with Java, install a package to allow us to toggle between Java versions and set our JAVA_HOME path automatically for us just by running a few simple commands.īefore we start, ensure that you have homebrew installed and that you have updated all dependencies (ie. For those that come from NodeJS, installing a new version of Node is as easy as installing nvm and running nvm install and calling it a day.
