Implicit Dependencies

There are several places in Eclipse where there is a button labeled Add Required Plug-ins, including the Plug-ins tab of the Target Platform Preferences page. When this button is pressed, PDE scans all the currently selected/checked plug-ins, recursively goes through their MANIFEST.MF dependencies and adds/checks any missing dependencies.

Implicit Dependencies are plug-ins that are required to run a product, but are not explicitly required by any other plug-ins in the MANIFEST.MF file. For these base plug-ins to be included in the result of the Add Required Plug-ins computation, they should be listed on the Implicit Dependencies tab.
