OBR should provide an API for resolving bundles dependencies regardless of
locally installed bundles
----------------------------------------------------------------------------------------------------
Key: FELIX-692
URL: https://issues.apache.org/jira/browse/FELIX-692
Project: Felix
Issue Type: Improvement
Components: Bundle Repository (OBR)
Reporter: Arjun Panday
Priority: Minor
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):
