今天用repo获取android源码：
../bin/repo init -u git://android.git.kernel.org/platform/manifest.git
出现问题：
问题一：
Traceback (most recent call last):
File "./repo", line 590, in <module>
main(sys.argv[1:])
File "./repo", line 557, in main
_Init(args)
File "./repo", line 176, in _Init
_CheckGitVersion()
File "./repo", line 205, in _CheckGitVersion
proc = subprocess.Popen(cmd, stdout=subprocess.PIPE)
File "/usr/lib/python2.5/subprocess.py", line 594, in __init__
errread, errwrite)
File "/usr/lib/python2.5/subprocess.py", line 1147, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
原因：没有装git，faint
解决：
sudo apt-get install git
sudo apt-get install git-core
问题二：
装好了git，再次运行：
Traceback (most recent call last):
File "/home/calvin/Android/Android2.0/source/.repo/repo/main.py", line 235, in <module>
_Main(sys.argv[1:])
File "/home/calvin/Android/Android2.0/source/.repo/repo/main.py", line 217, in _Main
repo._Run(argv)
File "/home/calvin/Android/Android2.0/source/.repo/repo/main.py", line 123, in _Run
cmd.Execute(copts, cargs)

p.stderr))
error.GitError: manifests var:
***
Please tell me who you are.
Run
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: empty ident <calvin@lihao-desktop.(none)> not allowed
解决：
看来的告知自己的身份才行。
运行：
[calvin@lihao-desktop ~/Android/Android2.0/source 18:44:28]$ git config --global user.email "lihao921@gmail.com"
[calvin@lihao-desktop ~/Android/Android2.0/source 18:44:28]$ git config --global user.name "Cavin Lee"
再运行repo：
[calvin@lihao-desktop ~/Android/Android2.0/source 18:45:00]$ ../bin/repo init -u git://android.git.kernel.org/platform/manifest.git
Your Name [Cavin Lee]:
Your Email [lihao921@gmail.com]:
Your identity is: Cavin Lee <lihao921@gmail.com>
is this correct [y/n]? y
Testing colorized output (for 'repo diff', 'repo status'):
black red green yellow blue magenta cyan white
bold dim ul reverse
Enable color display in this user account (y/n)? y
repo initialized in /home/calvin/Android/Android2.0/source（出现这个提示说明成功了）
接下来同步代码：
[calvin@lihao-desktop ~/Android/Android2.0/source 18:54:50]$ ../bin/repo sync
问题三：
同步代码时不断出现诸如
“remote end hung up unexpectedly“错误：
Fetching projects: 1% (2/158)
Initializing project platform/bootable/bootloader/legacy ...
fatal: The remote end hung up unexpectedly
error: Cannot fetch platform/bootable/bootloader/legacy
看样子是server的问题。
解决：
参考：
http://android.amberfog.com/?p=230
http://code.google.com/p/android/issues/detail?id=4488
sudo gedit .repo/repo/subcmds/sync.py
修改_Fetch函数为：
def _Fetch(self, projects):
fetched = set()
pm = Progress('Fetching projects', len(projects))
for project in projects:
pm.update()
while True:
if project.Sync_NetworkHalf():
fetched.add(project.gitdir)
break
else:
print >>sys.stderr, 'error: Cannot fetch %s' % project.name
pm.end()
return fetched
注意代码缩进问题，相应的代码段缩进要完全一样。
