Target Platform State
The Target Platform State View shows the current status of the resolver state in PDE.
Window > Show View > Other... > Plug-in Development > Target Platform State
Any plug-ins displayed with a red X are currently unresolved.
Expand an unresolved plug-in to reveal the unsatisfied constraints which result in the unresolved status.
When you open the children of a resolved plug-in, you will see its dependencies separated into imported packages and required bundles.
The child of each dependency is the plug-in which satisfies the particular dependency.
