下载android源码出错解决办法

获取Android源代码使用repo sync命令，但经常会出错，导致获取不了最新的代码。　　出现以下的类似错误：From https://android.googlesource.com/platform/manifest * [new branch] android-cts-2.3_r12 -> origin/android-cts-2.3_r12 * [new tag] android-cts-2.3_r12 -> android-cts-2.3_r12Exception in thread Thread-1:Traceback (most recent call last): File "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner self.run() File "/usr/lib/python2.6/threading.py", line 484, in run self.__target(*self.__args, **self.__kwargs) File "/cygdrive/f/OpenSource/Android/.repo/repo/subcmds/sync.py", line 186, in _FetchHelper current_branch_only=opt.current_branch_only) File "/cygdrive/f/OpenSource/Android/.repo/repo/project.py", line 929, in Sync_NetworkHalf current_branch_only=current_branch_only): File "/cygdrive/f/OpenSource/Android/.repo/repo/project.py", line 1428, in _RemoteFetch if GitCommand(self, cmd, bare=True, ssh_proxy=ssh_proxy).Wait() == 0: File "/cygdrive/f/OpenSource/Android/.repo/repo/git_command.py", line 215, in __init__ raise GitError('%s: %s' % (command[1], e))GitError: fetch: [Errno 13] Permission denied　　上网查了一番，发现到相应的工程运行一下git checkout -f就可以解决了。但是每次这样搞法也是费时费力啊。　　查了一下repo的命令参数，发现repo forall可以对所有项目执行一个命令。于是就有了以下的解决办法： repo forall -c git checkout -frepo sync -f
