How to install Java 8 on Mac

Tutorial: How to install Java 8 on Mac

I want to do some programming with the latest JavaFX, which requires Java 8. I’m using IntelliJ 13 CE and Mac OS X 9 Mavericks. I ran Oracle’s Java 8 installer, and the files look like they ended up at

/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk

but previous versions are at

/System/Library/Java/JavaFrameworks/jdk1.6....

Not sure why the latest installer puts this in /Library instead of /System/Library (nor what the difference is). But /usr/libexec/java_home doesn’t find 1.8, so all the posts I’ve found on how to set your current java version don’t work. I’ve tried adding a symbolic link to make it look like 1.8 is in the /System/Library... path, but it doesn’t help. /usr/libexec/java_home -V still only lists the old Java 1.6.

Ironically, the “Java” control panel under System Preferences shows only Java 1.8!

Why doesn’t Oracle’s installer put it where it really goes? And how can I work around this problem?

Solutions of How to install Java 8 on Mac

Solution 1: How to install Java 8 on Mac

Oracle has a poor record for making it easy to install and configure Java, but using Homebrew, the latest OpenJDK (Java 14) can be installed with:

brew install --cask adoptopenjdk8

For the many use cases depending on an older version (commonly Java 8), the AdoptOpenJDK project makes it possible with an extra step.

brew tap adoptopenjdk/openjdk
brew install --cask adoptopenjdk8

Existing users of Homebrew may encounter Error: Cask adoptopenjdk8 exists in multiple taps due to prior workarounds with different instructions. This can be solved by fully specifying the location with brew install --cask adoptopenjdk/openjdk/adoptopenjdk8.

Solution 4: How to install Java 8 on Mac

I just did this on my MBP, and had to use

$ brew tap homebrew/cask-versions
$ brew cask install java8

in order to get java8 to install.

Solution 5: How to install Java 8 on Mac

Assumption: Mac machine and you already have installed homebrew.

Install cask (with Homebrew 0.9.5 or higher, cask is included so skip this step):

$ brew tap caskroom/cask
$ brew tap caskroom/versions

To install latest java:

$ brew cask install java

To install java 8:

$ brew cask install adoptopenjdk/openjdk/adoptopenjdk8

If you want to install/manage multiple version then you can use ‘jenv’:

Install and configure jenv:

$ brew install jenv
$ echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(jenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile

Add the installed java to jenv:

$ jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
$ jenv add /Library/Java/JavaVirtualMachines/jdk1.11.0_2.jdk/Contents/Home

To see all the installed java:

$ jenv versions

The above command will give the list of installed java:

* system (set by /Users/lyncean/.jenv/version)
1.8
1.8.0.202-ea
oracle64-1.8.0.202-ea

Configure the java version which you want to use:

$ jenv global oracle64-1.6.0.39

To set JAVA_HOME:

$ jenv enable-plugin export
