How do I determine the update site/source of an installed Eclipse plugin?

How do I determine the update site/source of an installed Eclipse plugin?

For example, in one of my development versions of Eclipse I have the plugin org.hamcrest.library. From Help - About Eclips开发者_开发知识库e - Installation Details - Plug-ins I can determine that the provider is Eclipse.org, but is it possible to determine the feature or update site from where it came so I can install this in a separate version of Eclipse I have?

All third-party open source bundles that are used by Eclipse are managed by Orbit project. You can install them from Orbit Repository.
