How to set JAVA_HOME environment variable on Mac OS X 10.9?

I just purchased a brand new MacBook Pro.

This is my first MAC ever and I'm still trying to get the hang of navigating my way around.

Anyway, I'm also new to Java and I've been practicing on my Windows PC before it permanently died.

Now that I'm on this MAC, I installed my JDK and now I need to set the JAVA_HOME environment variable.

I have no idea what to do.

I tried following some of these guides and didn't get very far.

  1. Mkyong.com : How to set JAVA_HOME variable in Mac OSX

  2. YouTube : How to set environment variables on mac, linux, solaris, rhel

  3. YouTube : How to Set Environment Variables in Mac

I was able to locate the terminal and I think I created some multiple files. I'm getting messages like this:

(1) Another program may be editing the same file. If this is the case, be careful not to end up with two different instances of the same file when making changes. Quit, or continue with caution.

(2) An edit session for this file crashed. If this is the case, use ":recover" or "vim -r /Users/Erwin/.bash_profile" to recover the changes (see ":help recovery"). If you did this already, delete the swap file "/Users/Erwin/.bash_profile.sw p" to avoid this message.

Can somebody tell how to set Java in Mac OSX environment step by step?

Adrian Petrescu's answer is correct.

Additionally, you can verify your changes by running the following command in the terminal:

print $JAVA_HOME

If the changes were applied successfully, you'll see:

/Library/Java/JavaVirtualMachines/jdk-xx.jdk/Contents/Home

If the configuration is incorrect, nothing will be displayed.

First for MacOS let's check the java path go to finder:

command + space

type

finder

on the finder press the following key to open goto:

command+shift+g

and you can go to this path below, depending upon the java version, you can go to here;

/Library/Java/JavaVirtualMachines/jdk-23.jdk/Contents/Home

In case you didn't find java on this path: /Library/Java/JavaVirtualMachines/jdk-23.jdk/Contents/Home/

then you need to install java sdk for macOS, You can find it in java official page, and install ARM64 DMG Installer, based on your macOS.

After this check again this path as with above steps:

/Library/Java/JavaVirtualMachines/jdk-23.jdk/Contents/Home

then add this to your .zshrc file,

in case you don't have .zshrc file, go to terminal type

cd

then type

ls -al

still you didn't see the .zshrc file then make one using

nano ~/.zshrc

and press i then insert the path

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk23.jdk/Contents/Home

press escape :x and hit enter to save

now include this in source by typing following from the terminal:

source ~/.zshrc

let's check if it's saved or not, type

vim ~/.zshrc

again press i and press :x to exit

This should work!!!

if this doesn't work then make

nano ~/.bash_profile

and do the same process as we did.

my ~/.zshrc file looks like this:

export PATH="/opt/homebrew/bin:$PATH"
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-23.jdk/Contents/Home
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/emulator

For mac users https://stackoverflow.com/a/77953587/4792285

Install using homebrew https://formulae.brew.sh/formula/openjdk

brew install openjdk@21

OR

brew install openjdk@11

Then set up the .profile on your mac (/Users/your_username/.profile). If this file is hidden you may need to press Command + Shift + . (the period key) to make it visible.

add JAVA_HOME and update the PATH variable

export JAVA_HOME=$(/usr/libexec/java_home)
export PATH="$JAVA_HOME:$PATH"

open a new terminal and type

echo $JAVA_HOME
echo $PATH

to verify your change.

I had multiple versions of JDK installed, so what worked for me is that I manually configured my SpringToolSuite4 to use Java 11

In Mac OSX 10.5 or later, Apple recommends to set the $JAVA_HOME variable to /usr/libexec/java_home, just export $JAVA_HOME in file ~/.bash_profile or ~/.profile.

Open the terminal and run the below command.

$ vim .bash_profile

export JAVA_HOME=$(/usr/libexec/java_home)

Save and exit from Vim editor, then run the source command on .bash_profile

$ source .bash_profile

$ echo $JAVA_HOME

/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

I did it by putting

export JAVA_HOME=`/usr/libexec/java_home`

(backtics) in my .bashrc. See my comment on Adrian's answer.

Additionally update PATH variable as well.

PATH=$PATH:$JAVA_HOME/bin

More simply on a mac terminal with a modern OSX

$ vim ~/.zshrc

Type "a" to being editing, and then paste (ctrl + v):

$ JAVA_HOME=/usr/libexec/java_home

then hit "escape" and type exactly ":wq" in order to write to the file and quit vim mode.

Finally, when out of vim mode and back in your terminal, type

$ source ~/.zshrc

This will refresh so that your terminal is aware of the changes.

  • IMPORTANT * If you don't "source" the file, you won't see the changes in this terminal session.

Check the changes by typing

$ echo $JAVA_HOME

and you should see /usr/libexec/java_home

  • Open Terminal.
  • Confirm you have JDK by typing “which java”. ...
  • Check you have the needed version of Java, by typing “java -version”.
  • Set JAVA_HOME using this command in Terminal: export JAVA_HOME=/Library/Java/Home.
  • echo $JAVA_HOME on Terminal to confirm the path.

I'm able to solve this issue by setting JAVA_HOME in .bash_profile file

export JAVA_HOME=/usr/local/opt/openjdk@17

Note: I installed openjdk version 17 using 'brew'. I got this location from brew console. I'm using 'bash' instead of 'zsh' in my mac.

I resolved it on macOS Monterey by using the option provided by Google

Under Gradle JDK, choose the Embedded JDK option.

If you're using bash, all you have to do is:

echo export "JAVA_HOME=\$(/usr/libexec/java_home)" >> ~/.bash_profile

If you're using zsh (which probably means you're running macOS Catalina or newer), then it should instead be:

echo export "JAVA_HOME=\$(/usr/libexec/java_home)" >> ~/.zshrc

In either case, restart your shell.

If you have multiple JDK versions installed and you want it to be a specific one, you can use the -v flag to java_home like so:

echo export "JAVA_HOME=\$(/usr/libexec/java_home -v 1.7)" >> ~/.bash_profile

I just spent 2 hours setting this variable. The other answers did not work properly for me. I'm using macOS Catalina 10.15.4.

First, find your actual Java SDK Home directory:

/usr/libexec/java_home

Manually navigate there to make sure you don't have any mistakes due to incorrect versions, etc. For me, this was:

/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home

Next, edit your terminal's profile. If you're using zsh, this will be:

vim ~/.zshrc

If you're not using zsh, this will be:

vim ~/.bash_profile

Inside, add the following new line anywhere in the file:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home

Restart your terminal app (or source ~/.bash_profile), and it should work properly.

If you are using Zsh, then try to add this line in ~/.zshrc file & restart terminal.

export JAVA_HOME=$(/usr/libexec/java_home)

Since I'm using openjdk managed with sdkman, I added

sudo ln -sfn /path/to/my/installed/jdk/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

Adding this to your system lets java_home recognize your installed version of Java even when its not installed via standard packages

It is recommended to check default terminal shell before set JAVA_HOME environment variable, via following commands:

$ echo $SHELL
/bin/bash

If your default terminal is /bin/bash (Bash), then you should use @Adrian Petrescu method.

If your default terminal is /bin/zsh (Z Shell), then you should set these environment variable in ~/.zshenv file with following contents:

export JAVA_HOME="$(/usr/libexec/java_home)"

Similarly, any other terminal type not mentioned above, you should set environment variable in its respective terminal env file.

I got it working by adding to ~/.profile. Somehow after updating to El Capitan beta, it didnt work even though JAVA_HOME was defined in .bash_profile.

If there are any El Capitan beta users, try adding to .profile
