Debug#1
Refer to https://groups.google.com/forum/#!topic/android-building/0QkvGAQJ_Kg.
Adding alias to remotes fails to fix this issue.

Debug#2
 Add debug logs in manifest_xml.py

----------------------------------------------------------------------------------------------------------
Inference: "manifestUrl= None" is the problem.

Solution
Comparing 'git config -l' in .repo/manifests/ btwn OK and NG shows remote origin is missing in NG case.
'git remote add origin ....' fixes this issue.
