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...
