Situation


You want to submit a small patch to an Android source project.

You don't want to download the entire 14GB Android source code.

What you did


Initialize repo.

repo init -u https://android.googlesource.com/platform/manifest
Get https://gerrit.googlesource.com/git-repo

repo has been initialized in /home/ZWM

Sync the project.

repo sync platform/tools/base
Traceback (most recent call last):
  File "/home/ZWM/.repo/repo/main.py", line 500, in 
    _Main(sys.argv[1:])
  File "/home/ZWM/.repo/repo/main.py", line 476, in _Main
    result = repo._Run(argv) or 0
  File "/home/ZWM/.repo/repo/main.py", line 155, in _Run
    result = cmd.Execute(copts, cargs)
  File "/home/ZWM/.repo/repo/subcmds/sync.py", line 624, in Execute
    submodules_ok=opt.fetch_submodules)
  File "/home/ZWM/.repo/repo/command.py", line 184, in GetProjects
    raise InvalidProjectGroupsError(arg)
error.InvalidProjectGroupsError

InvalidProjectGroupsError? Whaaaaaat!?

Why did that happen



Let's open .repo/repo/command.py and go where the command failed.

        for project in projects:
          if not missing_ok and not project.Exists:
            raise NoSuchProjectError(arg)
          if not project.MatchesGroups(groups):
            raise InvalidProjectGroupsError(arg)

Apparently, a notion of group exists. Let's open the manifest and see in what group our project is.

notdefault? That doesn't sound good.

What you should have done


Init repo including group tools.

repo init -u https://android.googlesource.com/platform/manifest -g tools
[...]

repo sync platform/tools/base
