How to install the eclipse source code via “Eclipse Marketplace” or “Install New Software” option from eclipse menu?

Question

I am developing Eclipse RCP application, I am very new in RCP development & plugins development. I want to attach the eclipse source code in my eclipse (Kepler 4.3.2). Please suggest me step by step, how to attach the source code in my current eclipse?

Answer 1

Use 'Help > Install New Software...'

In 'Work with' enter the updates site for your release. This is http://download.eclipse.org/eclipse/updates/4.3 for Eclipse Kepler (4.3), http://download.eclipse.org/eclipse/updates/4.5 for the more current Eclipse Mars (4.5).

Select and install 'Eclipse Platform SDK' for the core source, or 'Eclipse SDK' for more complete source.

Once this is installed open the 'Preferences' and go to the 'Plug-in Development' page. Check the 'Include all plug-ins from target in Java search' option. This will include the source in Eclipse searches and the 'Open Type' dialog. Note: If you are using a 'Target Platform' the source need to be included in the target platform to get the search to work.

Alternatively most of the downloads from the Eclipse Projects page include the source plugins.

Answer 2

You can install source code as greg-449 said. but if you are a RCP developer its better download Eclipse for RCP and RAP Developers .
This package contains source code as well a complete set of tools for developers who want to create Eclipse plug-ins, Rich Client Applications or Remote Application Platform (RCP+RAP), plus Mylyn, the m2e Maven integration, and an XML editor. It contains the EGit tooling for accessing Git version control systems.
