RCP

Downloaded the Eclipse RCP SDK, eclipse-RCP-SDK-3.2-linux-gtk.tar.gz.

I extracted this file to:

~/development/java/rcp/target-book/

This is the start of the application I am building. It looks as if a separate workspace is required for each target environment. The Target Platform setup is a setting for the workspace rather than the project.

To connect my project to this target: Window, Preferences, Plug-in Development, Target Platform, set the Location field to your target folder:

/home/patrick/development/java/rcp/target-book/eclipse/

…and click Reload. The Environment tab sets up the JRE etc…
