查看可切换的分支
cd .repo/manifests
git branch -a | cut -d / -f 3
以 gingerbread-release 分支为例
repo init -b android-4.1.2_r1
repo sync (not needed if your local copy is up to date)
repo start android-4.1.2_r1 --all
查看当前的分支
repo branches
正在尝试这一种看看可不可以，执行repo sync后//我的好像还更新了

上面问题终于可以解决了，不用删除.repo, .repo已经8G了，怎么舍得删了重新同步呢？
再新建一个目录android4.3,执行 repo init -u git://github.com/CyanogenMod/android.git -b cm-10.2（这个源根据个人意愿不同而不同）
再把原来那个目录下的.repo覆盖到新建的android4.3目录下，再进行repo sync就OK了。
原来的目录可以删了
所有源码单独下载：https://android.googlesource.com/tools/repo/
软件共享：

另外，听说已经更新android 4.1源再执行repo init不会再重新下载所有源码
如果已经有android仓库但是还不是最新的，想切换到AndroidL分支分支
(1).cd .repo/manfiests && git branch -a | cut -d / -f 3

android-4.4_r1.2.0.1
android-4.4w_r1
android-5.0.0_r1
android-5.0.0_r2
(2).根据上面列表的选取android-5.0.0_r2
repo init -b android-5.0.0_r2
(3). repo sync
(4).全部切换到android-5.0.0_r2分支
repo start android-5.0.0_r2 --all
(5). repo branches
* android-5.0.0_r2 | in all projects
(6).cd external/jsmn && git branch
