[p2-dev] Fragments requiredCapability to the 'bundle'

[Thomas Hallgren <thomas@xxxxxxx>]

Hi,
We recently discovered that a lot of fragments express an explicit 
requirement to the 'bundle' capability and that all osgi.bundles 
provides this capability.

This creates a problem for us because we're generating the 
MetadataRepository based on a top group of things to install. We do that 
by adding all IU's that fulfill at least one required capability 
irrespective of versions. This approach breaks when a fragment requires 
the 'bundle' capability since we then must add every single bundle in 
the database to the MDR to be absolutely sure that nothing is missing.

I'm not sure I understand the thought behind the 'bundle' requirement. 
It's like saying that the fragment is happy as long as any bundle is 
present. Still, that information appears to be redundant since the 
fragment already has a special HostRequirement. Can someone please 
explain the thoughts behind this? I need to know in order to come up 
with a better scheme for how to limit the set of IU's to include.

Thanks,
Thomas Hallgren
