How to accept the Oracle JDK8 license automatically

echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | sudo /usr/bin/debconf-set-selections

How to set the Java environment variables

There is a package in our repository that automatically sets the Java 8 environment variables and sets JDK8 as the default JDK. To install it, use the following command:

apt-get install oracle-java8-set-default

If you've already installed oracle-java6-set-default or oracle-java7-set-default, they will be automatically removed when installing oracle-java7-set-default (and the environment variables will be set for Oracle Java 8 instead).
