Unfortunately in my case this didn’t end up uninstalling an older version of the JDK. It’s a rather manual approach but at least it is documented and the whole procedure consists of three commands. Removing the existing installationįortunately Oracle has uninstall instructions on their website. Oh, and installs the same JDK anyway, just without all the additional pointy clicky work. It’s just so much easier to get updates and update information all in one place. As I move the management of more development tools from manual management over to homebrew, I decided to use homebrew to manage my Java installation also. It was the typical “download from the Oracle website, then manually run the installer” deployment.

I’ve had a ‘manual’ install of JDK 8 on my Mac for quite a while, mainly to run Clojure. If you want to install a specific major version of the JDK (6 or 8 at the time of writing), I describe how to do that in this new blog post. _ Update: The title of this post isn’t quite correct as using the homebrew cask mentioned in this blog post will install the current major version of the Oracle JDK. The installation method described below will still work as it uses the non-versioned java cask, which installs the latest version of OpenJDK. On executing the command /usr/libexec/java_home -V we get the below output.Update II - : It looks like due to the recent licensing changes, the Java 8 JDK that brew used is not directly accessible anymore and likely behind some kind of paywall. Mac OS X requires us to set JAVA_HOME variable in ~/.bash_profile to /usr/libexec/java_home. Now lets install JDK 7 and JDK 8, they can be downloaded from here as any other software installed on Mac. Mac OS X 10.6 onward ship with JDK installed, here I have JDK 1.6 already installed. The command to verify the existing Java version is java -version and which java is used to check the location of the java command.

So in this post we shall see how to install multiple JDKs on Mac OS X, and also switch between them easily as and when required.

So I took a small risk and just tried out. It so happened that after watching JDK 8 in action in the GIDS Summit i was very much interested in trying out some of the features of JDK8, but i wasn’t sure of installing JDK 8 on my Mac because of the fact that the project i am working on is based on JDK 6 and will Mac allow me to uninstall JDK 8 and reinstall JDK 6 and in the process my OS shouldn’t be corrupted.
