Where is JAVA_HOME on macOS Mojave (10.14) to Lion (10.7)?

Question

Java is an optional package on the latest versions of macOS.

Yet once installed it appears like the JAVA_HOME environment variable is not set properly.

 

Answer 1

With the Java elective package or Oracle JDK installed, combining one of the subsequent lines to your ~/.bash_profile file will set the environment variable respectively.

export JAVA_HOME="$(/usr/libexec/java_home -v 1.6)"

or

export JAVA_HOME="$(/usr/libexec/java_home -v 1.7)"

or

export JAVA_HOME="$(/usr/libexec/java_home -v 1.8)"
