Orbit/Transition to Git Plan

Draft / Proposal
This is a draft plan being proposed. Please submit comments/feedback to orbit-dev@eclipse.org.

Goals

Migrate from hand crafted bundles in CVS to templated approach implemented by EBR
Publish bundles built from recipes as new (additional) p2 repository
Leaving all existing Orbit "R" builds in place
Provide a composite repository of old CVS based and new Git based bundles (allows for lazy migration of old bundles)

(July) Document plan and timeline
(July) Start publishing p2 repository with recipes on downloads.eclipse.org in addition to existing Orbit repositories
(August) Maven repository of IP approved libraries hosted at Eclipse.org (instead of consuming libraries from Maven Central)
(End of August) Announce availability of new "stream" and migration plan via cross-project
(September) Mars SR1
(October, after Mars SR1) Freeze CVS, stop building bundles out of CVS
(October, after Mars SR1) Every change must be done in Git now, i.e. missing recipes must be created first
(December) archive Orbit CVS

Downloads:

Orbit/New_Iplog_Design generate nice HTML download page for download.eclipse.org (based of p2 metadata?) (Orbit/New_Iplog_Design)
- will not: provide map files (they will go away), team project set, build logs (available in Hudson)
investigate test results ... porting or re-doing?
run CBI repository analyzes on p2 repo (done)
investigate OSGi repository support (index.xml)
investigate publishing CQ and license information into p2 metadata for bundle (from ip log) - publish CQ information along with list of bundles/jars (Orbit/New_Iplog_Design) (done, but could use improvements to method)

Build:

setup Maven repository at Eclipse.org to host IP approved libraries as source of truth (done)
consume IP approved libraries from Eclipse.org hosted Maven repository in addition to Maven Central
create and document process for adding IP approved libraries to such an Eclipse.org hosted Maven repositories
implement sign and pack (done)
publish p2 repo from recipe HIPP build on download.eclipse.org (done)
document requirements around the ip_log.xml

Future:

investigate addition of a final mirroring step using a comparator to only publish new/changed artifacts (bundles)
