本地Android源代码库下载源码

1. 安装repo

新建放置repo的bin目录

$ mkdir ~/bin
$ echo "export PATH=~/bin:\$PATH" >> ~/.bashrc
$ source ~/.bashrc

获取repo并赋予可执行权限（或者参考google官方网站）

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

2. 初始化一个repo客户端

创建一个目录用于放置需要下载的源代码

$ mkdir Android$ cd Android

运行repo init 初始化一个repo客户端；
获取一个最新的版本则直接指定manifest的URL地址$ repo init -u git://192.168.1.183/android/platform/manifest.git

推荐使用（初始化速度更快，要不然会受到https://gerrit.googlesource.com/git-repo连接失败的影响，原因：1.公司内可能https网络限制2.被GFW屏蔽）：
 $ repo init -u git://192.168.1.183/android/platform/manifest.git --repo-url=git://192.168.1.183/android/tools/repo.git

获取除了最新版本的其他版本，可以使用"-b"选项$ repo init -u git://192.168.1.183/android/platform/manifest.git -b android-4.1.1_r2

推荐使用（初始化速度更快，要不然会受到https://gerrit.googlesource.com/git-repo连接失败的影响，原因：1.公司内可能https网络限制2.被GFW屏蔽）：
 $ repo init -u git://192.168.1.183/android/platform/manifest.git -b android-4.1.1_r2 --repo-url=git://192.168.1.183/android/tools/repo.git

小技巧

可以手动指定repo sync所使用的线程数，默认是4个线程，比如使用8个线程 $ repo sync -j8

3. 下载代码

下载对应branch的代码，不指定branch默认是master的最新代码$ repo sync最终会出现：Fetching projects: 100% (344/344), done.Checking out files: 100% (9390/9390), done.out files:  25% (2388/9390)Checking out files: 100% (1304/1304), done.out files:  40% (529/1304)Checking out files: 100% (24607/24607), done.ut files:  50% (12308/24607)Checking out files: 100% (18917/18917), done.ut files:   0% (23/18917)Checking out files: 100% (36619/36619), done.ut files:  27% (10042/36619)Checking out files: 100% (96/96), done.Syncing work tree: 100% (344/344), done.表示repo sync 运行成功，如果失败请再次执行repo sync，repo会续传，继续下载代码。
