In this tutorial, I will go through how to set up the Odoo development environment on Ubuntu 22.04 with Eclipse as the IDE. This tutorial is valid for all Odoo versions from 8.0 to 16.0 and is effective for a fresh Ubuntu 22.04 Desktop with no pre-installed tools e.g. JDK, Python, or Eclipse. You may skip to the next step if you have already installed any of the above-mentioned tools.
