需要将 android AOSP 代码重置为 Lollipop
Need to reset android AOSP code to Lollipop
我已经下载了Android AOSP的当前主控Android 6.0源代码。
有没有办法使用 repo 将 master 设置为 Android 5.1，以便相应地设置所有 git 个存储库？
注意：我希望无需再次下载即可执行此操作。
To check out a branch other than "master", specify it with -b. For a
list of branches, see Source Code Tags and Builds.
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1

Note: I wish to do this without downloading again.
你可以试试：
repo init -b <manifest-branch>
repo sync -j8

I want to know if there is way to do it without downloading. The sync
would download from google servers.
documentation对sync命令说的真清楚：
Downloads new changes and updates the working files in your local
environment. If you run repo sync without any arguments, it will
synchronize the files for all the projects.
When you run repo sync, this is what happens:
If the project has never been synchronized, then repo sync is equivalent to git clone. All branches in the remote repository are
copied to the local project directory.
If the project has already been synchronized once, then repo sync is equivalent to:
git remote update
git rebase origin/<BRANCH>
where is the currently checked-out branch in the local
project directory. If the local branch is not tracking a branch in the
remote repository, then no synchronization will occur for the project.
If the git rebase operation results in merge conflicts, you will need to use the normal Git commands (for example, git rebase
--continue) to resolve the conflicts.
因为您已经同步了项目，所以 sync 命令等同于 rebase。
