Unable to use Java 1.8

Question

I'm having trouble using eclipse/intelliJ because whenever I try to check java version, this is what I will get. But java is present in the system preferences pane.

$ java -version
Unable to locate an executable at "/usr/libexec/java_home/bin/java" (-1)

Answer 1

If you're on Mac, do this:

export JAVA_HOME=$(/usr/libexec/java_home)

or:

export JAVA_HOME=`/usr/libexec/java_home`

Instead of this:

export JAVA_HOME=/usr/libexec/java_home

or:

export JAVA_HOME="/usr/libexec/java_home"

Answer 2

Looks like java is installed but classpath is not set. please try following command in terminal to set the java path.

export JAVA_HOME=/usr/libexec/java_home/bin/java
export PATH=$JAVA_HOME/bin:$PATH

Once this is done then check the java version. Hope it helps.
