This post describes how to configure the JAVA_HOME environment variable required by many enterprise tools, frameworks, and CMSes. For instance, Liferay, Tomcat, etc. will use this variable to work properly.
Run this command:
If the output is empty, then we don’t have the variable correctly set.
If you don’t know where the Java Development Kit (JDK) was installed, just run:
sudo find / -name javac
The output may be similar to this:
/usr/bin/javac /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/bin/javac /System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/javac find: /private/var/db/ConfigurationProfiles/Store: Operation not permitted find: /private/var/folders/y5/abbasdf/0/SafariFamily: Operation not permitted
Notice the second line, that is our JDK installation directory, so the directory we need to use is this one: /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/
Let’s open the file (if don’t exist, just create it):
Add the JAVA_HOME variable at the end of ~/.bash_profile
Save the file ~/.bash_profile (in nano just press Control + O followed by Control + X to close the file). Finally, let’s review or configuration by typing:
This command should now print the correct JAVA_HOME:
If you don’t see your environment variable, please close all your terminal windows and re-start them so you have a “fresh” start.
Sweet, isn’t it?
See you next time.
