Installing Java 8 and Eclipse on Mac OS X. This page tells you how to download and install Java 8 and Eclipse on Mac OS X, and how to configure Eclipse. Scroll down until you see a heading beginning 'Java SE 8u65/8u66.' On the right, you'll see a Download button under the JDK header. The next screen will look like this. Determining the Default Version of the JDK. If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app.

Update III – 2020-05-06: There are now alternatives available to using the official Oracle Java 8 JDK. I’m currently using AdoptOpenJDK‘s version that you can install by usingbrew cask install adoptopenjdk8. So far this seems to do everything I need a JDK for. Just keep in mind that I mostly use my JDKs when I’m working on Clojure code.

Update II – 2019-05-07: 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. The installation method described below will still work as it uses the non-versioned java cask, which installs the latest version of OpenJDK.

Update: The title of this post isn’t quite correct – using the homebrew cask mentioned in this blog post will install the current major version of the Oracle JDK. 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.

I’ve had a ‘manual’ install of JDK 8 on my Mac for quite a while, mainly to run Clojure. It was the typical “download from the Oracle website, then manually run the installer” deployment. 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’s just so much easier to get updates and update information all in one place. Oh, and installs the same JDK anyway, just without all the additional pointy clicky work.

Removing the existing installation

Fortunately Oracle has uninstall operations on their website. It’s a rather manual approach but at least it is documented and the whole procedure consists of three commands. Unfortunately in my case this didn’t end up uninstalling an older version of the JDK. For some reason, I had ended up with both 1.8.0_60 and 1.8.0_131 installed on my machine, and Oracle’s uninstall instructions didn’t touch the 1.8.0_60 install in /System/Library/Frameworks/JavaVM.framework. I suspect this is an older JDK brought over from the Yosemite install and the consensus on the Internet I could find suggest to leave that alone as the system needs those.

Apparently in older versions of OS X is was possible to run /usr/libexec/java_home -uninstall to get rid of a Java install, but that option does not appear to work in OS X Sierra anymore

Installing Java using Homebrew

Jdk 8 For Mac

The installation via homebrew is about as simple as expected. I have cask installed already, so for me it’s a simple matter of running

and it will install the latest Oracle JDK. You can use

to verify which version it will install.

If you haven’t got homebrew installed, follow the installation instructions on docs.brew.sh and also make sure that you install cask:

After re-installing the JDK using homebrew, java_home also finally reports the correct version:

After upgrading to a newer version of Mac OS X (Yosemite 10.10 and El Capitan 10.11) or macOS (Sierra 10.12 and High Sierra 10.13), you may end up getting an annoying new pop-up message whenever you start your computer. It says, “To use the java command-line tool, you need to install a JDK.” It asks you to click “More Info” and visit the JDK (Java Developer Kit) download website.

The reason you’re receiving this message is due to the removal of Java support in newer versions of OS X for security reasons. Older software such as Adobe Photoshop and Illustrator requires legacy Java support. Without a compatible Java command-line tool for these software, you’ll get this pop-up every time you turn on your Mac computer.

When you visit the download website to update Java, you find that the issue isn’t resolved! You’re still getting the same pop-up. This isn’t a complicated issue to fix, but it is an indirect one. The problem is that you’re not being routed to the correct download website when you click “More Info.”

Apple could have remedied this issue by programming the “More Info” button to direct you to the right fix. Here are the steps you can take to finally rid yourself of this pop-up:
