set mac jdk version to 1.8

java, macos

Solution

To set Java to 1.8 for your shell environment, put this in your ~/.bash_profile:

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

Problem

I have searched several ways to change JDK version on mac. ``` $/usr/libexec/java_home ``` And I got ``` /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home ``` I tried ``` $export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home ``` also tried ``` /usr/libexec/java_home 1.8.0_31 --exec javac -version ``` then I run ``` $echo $JAVA_HOME ``` /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home then I re-check java -version ``` $java -version java version "1.7.0_67" Java(TM) SE Runtime Environment (build 1.7.0_67-b01) Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode) ``` How I can really change java -version on my mac.
