As you know, there is a list of several hundred projects in https://android.googlesource.com/. I\'d like to download them all in windows machine. According to Google\'s document

    With one click, download the latest code as .tar.gz file, from here https://android.googlesource.com/platform/frameworks/base/+archive/master.tar.gz, the android could be found under core folder

    Edit
    Alternative here:
    http://grepcode.com/project/repository.grepcode.com/java/ext/com.google.android/android/

    Just select the version then a download options within.

    If you consider, as an example, this other program "sympy" which also needs git bash and python, it is only a matter to add python to your PATH prior to launching the git bash session.

    Install Python from:

    http://python.org/download/

    by downloading the "Python 2.7 Windows installer" (or Python 2.6 or 2.5) and running it.
    Add python directory to your system environment path variable
    (My Computer -> Advanced -> Environment Variables -> Path -> Edit).

    Note that the repo script itself must be in the path, as mentioned in the Version Control page of android:

    Repo is a repository management tool that we built on top of Git. Repo unifies the many Git repositories when necessary, does the uploads to our revision control system, and automates parts of the Android development workflow.
    Repo is not meant to replace Git, only to make it easier to work with Git in the context of Android.
    The repo command is an executable Python script that you can put anywhere in your path.

    This answer explains how to fix this error:

    fatal: unable to start c:\path\.repo\repo/main.py
    fatal: [Errno 8] Exec format error
    

    Summary: I finally used the python packaged by Cygwin.
    Details: Below is the full story.

    The tip from the repo bug tracking is to add '/c/app/Python27/python ':

    • line 136 in v1.20
      REPO_MAIN = '/c/app/Python27/python ' + S_repo + '/main.py'
    • line 735 in v1.20 (beginning of function main)
      wrapper_path = '/c/app/Python27/python ' + os.path.abspath(__file__)

    But we get the error TypeError: coercing to Unicode: need string or buffer, NoneType found

    Therefore I reverted these changes above and performed the other changes below (on version 1.20):

    • line 136, replaced single slash by double back-slash:
      REPO_MAIN = S_repo + '\\main.py'
    • line 766, added python absolute path as first element of me:
      me = ['C:\\app\\Python27\\python.exe', repo_main,
      '--repo-dir=%s' % rel_repo_dir,
      '--wrapper-version=%s' % ver_str,
      '--wrapper-path=%s' % wrapper_path,
      '--']
    • line 776, replaced os.execv(repo_main, me) by
      os.execv('C:\\app\\Python27\\python.exe', me)

    However we get still an error:

    $ Traceback (most recent call last):
      File "c:\path\.repo\repo\main.py", line 39, in <module>
        from subcmds.version import Version
      File "c:\path\.repo\repo\subcmds\__init__.py", line 36, in <module>
        ['%s' % name])
      File "c:\path\.repo\repo\subcmds\forall.py", line 17, in <module>
        import fcntl
    ImportError: No module named fcntl
    

    The Python v2.7 fcntl documentation says fcntl is available for platform Unix only.

    I finally reverted again all changes in repo script and installed Cygwin including its python and git packages: it succeeded as a charm.

    But, as the symlinks simulated by Cygwin are not recognized by the MSysGit, we have to use the Cygwin git. And GUIs on top of git are not fully compliant with Cygwin git...

    (see also my other post)

    Edit:
    Cygwin can use native NTFS symlinks (just set CYGWIN=winsymlinks:native and be Admin). Therefore MSysGit can be used and any other GUI based on it :-)
