As a developer, I like to look at the source code for the libraries I use in order to understand if what I am doing is the best way to implement it or not. Though Eclipse, by default, comes with features to develop plugins, it doesn’t come with the source code for this. Getting the source is a simple, 3 step process!
Help > Install new Software
Work with ‘The Eclipse Project Updates’ (not the main site!)
Install the following items
Eclipse RCP Plug-in Developer Resources
Eclipse PDE Plug-in Developer Resources
Eclipse Platform Plug-in Developer Resources
Equinox p2 Core Function Source
Eclipse JDT Plug-in Developer Resources
Welcome to the source, Neo!
Updated (29/11/2013): More source projects added! Seems there is a nice StackOverflow question on the same (which doesn’t have an answer which meets my satisfaction). I’ll keep my post in sync with my answer on StackOverflow.Created: Tue, 08 Oct 2013 12:11:11 +0530
