AOSP源码下载方法，解决repo sync错误：android-13.0.0_r82
篇头
最近写文章，反复多次折腾AOSP代码，因通过网络repo sync aosp代码，能一次顺利下载的概率很低，以前就经常遇到，但从未总结，导致自己也要回头检索方法，所以觉得可以总结一下，涉及下载最新、各分支AOSP代码的方法，以及如何处理所遇到的同步错误及其解决方法，现分享给大家~
一、下载源码包及repo
- 包含 aosp-latest.tar 和 repo程序
- 下载TAG包，可以节约很多时间
（1）下载初始化包，约 60GB 数据，建议复制地址，直接使用迅雷下载
szhou@bc-R01:~/works$curl -OC - https://mirrors.tuna.tsinghua.edu.cn/aosp-monthly/aosp-latest.tar
（2）解压
szhou@bc-R01:~/works$ mkdir aosp
szhou@bc-R01:~/works$ tar -xvf aosp-latest.tar -C aosp/
（3）下载repo
szhou@bc-R01:~/works/aosp$ mkdir bin
szhou@bc-R01:~/works/aosp$ curl https://storage.googleapis.com/git-repo-downloads/repo > bin/repo
szhou@bc-R01:~/works/aosp$ curl https://storage.googleapis.com/git-repo-downloads/repo > bin/repo

Dload Upload Total Spent Left Speed
100 48143 100 48143 0 0 48336 0 --:--:-- --:--:-- --:--:-- 48287
（4）部署repo
szhou@bc-R01:~/works/aosp$ chmod a+x bin/repo
szhou@bc-R01:~/works/aosp$ sudo cp bin/repo /usr/bin/
[sudo] password for szhou:
szhou@bc-R01:~/works/aosp$
二、代码更新
2.1 目录情况
- 解压后，在aosp目录下，只有.repo目录，还需要同步代码和检出代码
szhou@bc-R01:~/works/aosp/aosp$ ls -al
total 12
drwxr-xr-x 3 szhou szhou 4096 10月 1 00:00 .
drwxrwxr-x 4 szhou szhou 4096 12月 24 00:39 ..
drwxr-xr-x 7 szhou szhou 4096 10月 1 00:45 .repo
szhou@bc-R01:~/works/aosp/aosp$
2.2 更新.repo/repo 程序
- 第一次更新AOSP源码，记得执行此步骤，可以减少后续repo sync错误
szhou@bc-R01:~/works/aosp/aosp$ ls -al
total 12
drwxr-xr-x 3 szhou szhou 4096 10月 1 00:00 .
drwxrwxr-x 4 szhou szhou 4096 12月 24 00:39 ..
drwxr-xr-x 7 szhou szhou 4096 10月 1 00:45 .repo
szhou@bc-R01:~/works/aosp/aosp$ cd .repo/repo/
szhou@bc-R01:~/works/aosp/aosp/.repo/repo$ git pull

操作如下图所示
2.3 查看可用分支
- 可见13的最新版本为：remotes/origin/android-13.0.0_r82， 即r82版本
- 通过修改grep后的过滤条件，也可以查看其他版本情况
szhou@bc-R01:~/works/aosp/aosp/.repo/manifests.git$ git branch -av | grep android-13
remotes/origin/android-13.0.0_r1 0f42cde46 Manifest for Android 13.0.0 Release 1 (TP1A.220624.014)

remotes/origin/android-13.0.0_r82 ed487956f Manifest for Android 13.0.0 Release 82
remotes/origin/android-13.0.0_r9 0bac787fd Manifest for Android 13.0.0 Release 9
szhou@bc-R01:~/works/aosp/aosp/.repo/manifests.git$
操作如下图所示
2.4 配置Python
- 当前AOSP代码需要Python 3.6以上版本，才可正常使用
2.4.1 Python版本导致的repo sync错误
szhou@bc-R01:~/works/aosp/aosp/.repo/manifests.git$ cd ../..
szhou@bc-R01:~/works/aosp/aosp$ repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-13.0.0_r82
File "/usr/bin/repo", line 51
def print(self, *args, **kwargs):
^
SyntaxError: invalid syntax
szhou@bc-R01:~/works/aosp/aosp$ python --version
Python 2.7.18
szhou@bc-R01:~/works/aosp/aosp$
2.4.2 查看可用的Python版本
- 常用Python，至少需安装2.7和3.6以上，两个版本
sudo apt-get install python2.7
（1）查看已安装的Python有哪些版本
szhou@bc-R01:~/works/aosp/aosp$ ls -l /usr/bin/python*
lrwxrwxrwx 1 root root 24 12月 10 20:34 /usr/bin/python -> /etc/alternatives/python
lrwxrwxrwx 1 root root 9 3月 13 2020 /usr/bin/python2 -> python2.7

lrwxrwxrwx 1 root root 14 4月 15 2020 /usr/bin/python-config -> python2-config
szhou@bc-R01:~/works/aosp/aosp$
2.4.3 配置多Python版本支持
- 本人系统中已安装2.7和3.8两个版本
（1）配置多版本支持
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.8 2
（2）执行 --config python后，选择Python3.8, 编号为2
szhou@bc-R01:~/works/aosp/aosp$ sudo update-alternatives --config python
[sudo] password for szhou:
There are 2 choices for the alternative python (providing /usr/bin/python).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/python3.8 2 auto mode
* 1 /usr/bin/python2.7 1 manual mode
2 /usr/bin/python3.8 2 manual mode
Press <enter> to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/bin/python3.8 to provide /usr/bin/python (python) in manual mode
szhou@bc-R01:~/works/aosp/aosp$
（3）查看版本设置情况
szhou@bc-R01:~/works/aosp/aosp$ python --version
Python 3.8.10
szhou@bc-R01:~/works/aosp/aosp$
2.5 repo init 初始化分支
- 为了节约repo sync时间，我们可以选定只同步目标分支：android-13.0.0_r82
repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-13.0.0_r82
2.6 repo sync
- 加上 -c 参数，仅同步当前android-13.0.0_r82分支，节约下载时间
szhou@bc-R01:~/works/aosp/aosp$ repo sync -c
三、解决repo sync 错误
3.1 Python 版本引起的错误
- 解决办法： 建议切换到3.8及以上版本
- 多版本支持，请查看本文第2.4.1节
szhou@bc-R01:~/works/aosp/aosp/.repo/manifests.git$ cd ../..
szhou@bc-R01:~/works/aosp/aosp$ repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-13.0.0_r82
File "/usr/bin/repo", line 51
def print(self, *args, **kwargs):
^
SyntaxError: invalid syntax
szhou@bc-R01:~/works/aosp/aosp$ python --version
Python 2.7.18
szhou@bc-R01:~/works/aosp/aosp$
3.2 repo脚本偏旧导致的错误
- 解决办法：切换到aosp/.repo/repo目录下，执行git pull
szhou@oa-R630:~/works/aosp$ /home/szhou/Downloads/aosp/bin/repo sync -c
Fetching: 100% (1146/1146), done in 11m43.689s
info: A new version of repo is available
repo: Updating release signing keys to keyset ver 2.3
warning: repo is not tracking a remote branch, so it will not receive updates

Repo command failed: RepoUnhandledExceptionError
szhou@oa-R630:~/works/aosp$
szhou@oa-R630:~/works/aosp/.repo/repo$ git pull
3.3 repo sync 数据错误
3.3.1 类型1：error: in sync -lc: revision refs xxx
- 解决办法：
- （1）找到事故目标： .repo/projects/device 或 .repo/projects/device /google/raviole-kernel
- （2）删除 rm -rf .repo/projects/device
- （3）更准确点：rm -rf .repo/projects/device /google/raviole-kernel
- （4）继续repo sync -c 同步代码
szhou@oa-R630:~/works/aosp$ /home/szhou/Downloads/aosp/bin/repo sync -c
error: Cannot checkout device/google/raviole-kernel: ManifestInvalidRevisionError: revision refs/tags/android-13.0.0_r82 in device/google/raviole-kernel not found

3.3.1 类型2：Unable to fully sync the tree
- 如下，虽然同步完成了，但提示了一些错误
- 解决办法：
- （1）锁定Failing repos目标
- （2）逐个删除，例如 rm -rf device/generic/trusty device/generic/uml art ……
- （3）继续执行 repo sync -c， 直至无错误100%完成同步
