How to set JAVA_HOME in Mac permanently?

You can use /usr/libexec/java_home -v <version you want> to get the path you need for JAVA_HOME. For instance, to get the path to the 1.7 JDK you can run /usr/libexec/java_home -v 1.7 and it will return the path to the JDK. In your .profile or .bash_profile just add

export JAVA_HOME=`/usr/libexec/java_home -v <version>`

and you should be good. Alternatively, try and convince the maintainers of java tools you use to make use of this method to get the version they need.

To open '.bash_profile' type the following in terminal :

nano ~/.bash_profile 

and add the following line to the file:

export JAVA_HOME=`/usr/libexec/java_home -v <version>`

Press CTRL+X to exit the bash. Press 'Y' to save changes.

To check whether the path has been added, type following in terminal:

source ~/.bash_profileecho $JAVA_HOME

I was facing the same issue in MAC Catalina, If I edit .bash_profile i found export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_201.jdk/Contents/HomeBut When I run terminal echo $JAVA_HOME it was returning empty, Later I found that the file .zshrc was missing I created this file with

touch .zshrc 

Then edit it by nano .zshrc and wrote

source ~/.bash_profile

Which solves my issue permanently
