How to obtain the version of a custom feature at runtime?

There is a similar question on SE, but the answers only work for detecting the versions of available plug-ins.

I however look for a way to retrieve the version number of a user-defined feature at runtime.

Let's say I defined a feature com.me.prog.prod.feature that defines plugin dependencies and is later used in a product definition com.me.prog.prod.product. When launching com.me.prog.prod.product I want to be able to retrieve the version information of com.me.prog.prod.feature as I want to use it for top-level program versioning.

Is there a way to do this using Eclipse RCP framework code?

The following should get you the feature version number:

String version = null;
IBundleGroupProvider[] providers = Platform.getBundleGroupProviders();
for (IBundleGroupProvider provider : providers) {
    IBundleGroup[] groups = provider.getBundleGroups();
    for (IBundleGroup group : groups) {
        if ("com.me.prog.prod.feature".equals(group.getIdentifier())) {
            version = group.getVersion();
        }
    }
}

You will have to give the specific feature name in there as a plugin could potentially belong to more than one feature.
