Richard S. Hall commented on FELIX-692:
---------------------------------------
In responding to Arjun's comments, I realized my comment about the patch missed
the getSystemRepository() and getLocalRepository() methods added
RepositoryAdmin. The issue here is the same, we can't expose these methods on
this interface, since these are implementation concepts. As such, like Arjun
indicated in his patch, we need some other way for clients to identifier the
local and system repositories.
> OBR should provide an API for resolving bundles dependencies regardless of
> locally installed bundles

> URL: https://issues.apache.org/jira/browse/FELIX-692
> Project: Felix
> Issue Type: Improvement
> Components: Bundle Repository (OBR)
> Reporter: Arjun Panday
> Assignee: Guillaume Nodet
> Priority: Minor
> Fix For: bundlerepository-1.6.0

> Attachments: bundlerepository.tgz

> Currently the dependencies that are installed locally are stripped from the
> OBR Resolver response, because it is assumed that the new bundles are to be
> installed locally. But i cannot use the OBR to launch a separate JVM or store
> the result for later reference...
> It would be interesting to have a pure Resolver API, distinct from the OBR's
> "installation process".
> And/Or, as Richard Hall suggested, the OBR could provide better control over
> the repositories used during the resolve process (specifically the local
> repository).
> (see thread "OBR and the referral tag" in [email protected])
> Merely as a hint and for what it's worth, here's how i slightly modified the
> Resolver in bundlerepository 1.0.3 to serve my purpose (avoid ignoring
> locally installed bundles):
