The Target Definition Editor is used to edit target definition files in the workspace, which should end with the extension ".target". Target definition files can be created using the New Target Definition Wizard or by moving them to the workspace on the Target Platform Preference Page.
The editor consists of four pages:
At the top of each of the three first pages in the editor there is a link Set as Target Platform. Activating this link will set this target definition as the active target platform. To see what your active target platform is, use the Target Platform Preference Page.
Before the contents of a target can be edited and before a target definition can be set as the active target platform it must be resolved. When a target definition is resolved, the definition's locations are searched for plug-ins. Depending on the type of locations in the target, this can involved searching a directory, reading the metadata for an installation, reading a feature, or downloading from a remote site. During resolution a background job will be run. When it completes the editor will be updated with any problems that occurred.
