Android Build Configs in GIT
android-build jobs currently use the build configuration field in jenkins to maintain a few options needed to reproduce the build. The configuration data discussed here includes information about manifest branch location, but also things like build optimization flags, toolchain parameterizations and source overlay URLs.
This blueprint aims at adding support to android-build to pull such config data from a git repository.
For that the following changes are developed:
1. configurations of all "official" baseline builds are getting moved to git
2. android-build tools will grow config options that specify a git maintained config location and source it's configurations from there
3. android-build tools job will export a formatted build-config.txt artifact that contains the information to reproduce a build; at least the repo url, revid and optionally a gitweb URL for the repo of the config that was used
4. a follow up blueprint will get filed to initiate the next stage: improving the build frontend to present and link to the right git web directly on the web UI.

Whiteboard
[asac, Fri 11, 2011]: drafted; replayed the current work done.
[asac, Fri 11, 2011]: build configs for official tip builds has been created here: http://
[dzin, Jun 7, 2012]: not started in 12.05, moving to 12.06
[danilo, Jun 26, 2012]: moving to backlog, no time for this.
Meta:
Headline: Android build service offers build job parameterization in git
Acceptance: Build configs are maintained in a gerrit managed git tree; build revision will be be exported in a build-meta.txt file that also ships other info needed to locally reproduce. build-meta.txt file format is defined. build-meta.txt format allows improving the format over time through specifying a fromat-spec version. Blueprints for improving the build frontend to display this info conveniently as well as for fixing the convenient build scripts to really reproduce a build using the build-meta info have been filed. asac has signed off the follow up blueprints.
