It seems all good things start with installing JDK 8... 

This guide covers installing JDK 8 on several Linux distros I use.

Guide

You can install can install openJDK or Oracle's official JDK (note you only need one of these).  I 

Ubuntu / Debian

To install openJDK:

sudo apt-get update
sudo apt-get install default-jdk

To install Oracle JDK8, you can add Oracle's ppa and do the install:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo update-alternatives --config java

Arch / Manjaro

In Arch / Manjaro, we can install the openJDK with pacman:

sudo pacman -S jdk8-openjdk

For oracle's JDK 8, we'll need to install with yaourt or packer as it is not in the normal pacman repos:

yaourt jdk

Then select jdk8 for the options that follows (was item 42 for me).
