How to set the Java path installed by Homebrew?
I use the method suggested by Maarten Mulders.
I added the following to my bash profile (the file .bash_profile
in my home directory).
alias j9="export JAVA_HOME=`/usr/libexec/java_home -v 9`; java -version"
alias j8="export JAVA_HOME=`/usr/libexec/java_home -v 1.8`; java -version"
alias j7="export JAVA_HOME=`/usr/libexec/java_home -v 1.7`; java -version"
When I want to change to a Java version, I simply execute j7
in the terminal.

Java 9 is installed in my MacBook (OS X 10.11 El Capitan). As I needed Java 8, I've installed it using Homebrew.
$ brew cask install java8
However, the Java version is still 9 in the terminal.
$ java -version java version "9" Java(TM) SE Runtime Environment (build 9+181) Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)
The install location of the current Java seems to be in
/System/Library/Frameworks/.../Commands
$ ls -la /usr/bin/java lrwxr-xr-x 1 root wheel 74 Sep 23 2017 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
Homebrew seems to have installed Java 8 in
/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home/bin/
Of course I could just prepend the above path to the
PATH
environment variable in~/.profile
, but I wanted to know whether there is a more robust way of setting the path for the older Java version. -
