[eclipse-dev] Target Platform Changes

Dear Eclipse Plug-in Developers,

In 3.5M5, the PDE team added a new experimental preference page supporting managing and editing of multiple target platforms: Plug-in Development > Target Platform (Experimental). In the latest i-build (20090224-0800), this page has become the default way of managing target platforms and the old page was removed. The page displays all targets defined in the workspace. You can change the target platform used to build workspace plug-ins by checking it in the table. A wizard allows you to add and edit target platform definitions. You can seed a target platform from existing templates (for example, an RCP application), default settings, current target platform settings or start from scratch. Target definitions created from the preference page, by default, are stored locally in your workspace metadata. You can add plug-ins to a target definition from various sources: a directory, an installation (this looks at the list of INSTALLED bundles), a feature, or a repository (update site). You can also scope which plug-ins or features make up a target definition. Also, you can create a target definition from the New -> File -> Plug-in Development -> Target Definition wizard and share it with your friends (use variables if you want a target definition to be shareable).

Please note that this is a change to how people worked with target platforms before. In the past, you just pointed to a directory and magic happened. This was a very brittle way of working with targets and wasn't conducive to sharing with teammates. In the future, look for PDE to support target platform materialization from p2 repositories and the much requested feature of multiple targets per workspace.

If you find any issues with the new target platform story, issues with the new target workflow or have suggestions, please file a bug against PDE with a starting summary of "[target] xxx"

Thank you for using PDE.
