How to find dependencies of plug-in? [message #332818]

Hello,

Could someone tell me how to programmatically find the dependencies
(required plug-ins) of a plug-in (say org.eclipse.ui for instance)?

I tried using class org.osgi.framework.Bundle, but still have had no luck.

Thanks in advance!

I looked around for you seems like you want to take a look at
Bundle.getHeaders() as I think there is a header that specifies the list
of dependent plugins declared in the plugin's MANIFEST.
http://www.ibm.com/developerworks/library/os-eclipse-bundlem gmt/index.html
has a table of headers and the Require-Bundle is the header that I think
should contain that information. Hope that helps. - Duncan

You need to work with BundleDescription objects. And then use
StateHelper which has a number of interesting methods.

To get BundleDescription objects, you will need to use the PlatformAdmin
service. The easiest way to get the service is
Platform#getPlatformAdmin().
Then you need the State (PlatformAdmin#getState()), the state has
State#getBundle(long) iwhere you can pass in your Bundle#getBundleId().
