1. 介绍

鉴于很多项目以前是使用SVN进行管理的，最近打算逐步将一些代码开源出来，以便需要的朋友使用。这就不可避免的出现了SVN代码如何转到Github上的问题。

主要的问题是希望之前的上传记录不要丢失，这里结合一个例子正好整理和测试下命令是否可以正常的将SVN代码转到Github进行托管。

2. autoAudioTest之SVN转Github步骤

Step 1 工作环境(ubuntu)

$ uname -a
Linux daniel-ThinkPad-SL410 5.15.0-58-generic #64~20.04.1-Ubuntu SMP Fri Jan 6 16:42:31 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.5 LTS
Release:        20.04
Codename:       focal

Step 2 安装升级必要软件

这里可能涉及一些工作环境之前已经预装的软件，比如：java等

注：下面这些软件是必须的，就特地强调一下。

$ mkdir GitMigration
$ cd GitMigration
$ sudo apt-get install subversion git git-svn

Step 3 转换脚本

Download svn-migration-scripts.jar

$ wget https://bitbucket.org/atlassian/svn-migration-scripts/downloads/svn-migration-scripts.jar

注：感觉这个并不重要，因为实际对工程项目了解的话，看下日志记录，可以自己写那个author.txt文档。

Step 4 检查软件运行环境

$ java -jar svn-migration-scripts.jar verify
svn-migration-scripts: using version 0.1.56bbc7f
Git: using version 2.25.1
Subversion: using version 1.13.0
git-svn: using version 2.25.1

Step 5 生成authors.txt

主要目的是为了导出并修改后续github中每个commit的作者名字及联系方式

$ java -jar svn-migration-scripts.jar authors svn://192.168.68.200/BloodDiamond-Echo > authors.txt
$ cat authors.txt
lida = lida <lida@mycompany.com>
root = root <root@mycompany.com>

修改为如下格式：

$ vi authors.txt
$ cat authors.txt
lida = lida <lida-mail@163.com>
root = root <lida_mail@163.com>

Step 6 SVN转换Git格式

$ git svn clone --stdlayout --authors-file=./authors.txt svn://192.168.68.200/BloodDiamond-Echo autoAudioTest

creating empty directory: thirdparty


$ cd autoAudioTest/
$ git branch -a
* master
  remotes/origin/trunk

注：鉴于我们通常是标准的SVN目录管理格式，所以用常规方法即可。

Step 7 Github新建空工程

这一步是Github的操作，这里就忽略了。

注：如果有不太清楚的同学，点击Github上自己【个人头像】–>【Your repositoris】–>【New】新建。

Step 8 Git提交已有工程

进入新建空白工程【code】页面，提示几种新建工程的方法：

Step 9 Git提交经转换的SVN工程

$ git remote add origin git@github.com:lida2003/autoAudioTest.git
$ git remote -v
origin  git@github.com:lida2003/autoAudioTest.git (fetch)
origin  git@github.com:lida2003/autoAudioTest.git (push)
$ git branch -m master main
$ git push --set-upstream origin main

remote: error: See http://git.io/iEPt8g for more information.
remote: error: File release/autoAudioTest_v1.1.8.exe is 145.55 MB; this exceeds GitHub's file size limit of 100.00 MB
remote: error: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com.
To github.com:lida2003/autoAudioTest.git
 ! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'git@github.com:lida2003/autoAudioTest.git'

Step 10 解决GH001: Large files detected

看下日志说的“release/autoAudioTest_v1.1.8.exe”是那次提交引入的。
