Galileo release URL: The Eclipse framework is released annually as a collected
and tested repository. Each release has a different name relating to celestial objects, so far moons of planets in the solar system. You should use the repository URL for the release you are using. The name is made up of "download.eclipse.org" and "/releases/galileo" in this case, but would obviously change if you used a different version of eclipse.
