同步源码，问题重现：

分析问题，寻找方案：
1、问题所在：主要是repo的问题，只需要重新下载repo即可。
2、下载repo需要IP代理，http://www.cnblogs.com/dinphy/p/5619854.html
3、终端输入命令重新下载repo并初始化：
#新建bin目录 mkdir ~/bin #指定路径 PATH=~/bin:$PATH #下载repo，并移动到bin目录下 curl https://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo #给repo赋予读写权限 chmod a+x ~/bin/repo
4、回到项目的目录，重新初始化源码，然后repo sync
5、OK，完美结束。
