无论如何，git-svn 很好地支持了这一点，只是在通常的 git svn 克隆上略有不同。
我们使用稍微不同的标准项目/主干|分支|标签而不是标准，parent/trunk|branches|tags/project
因此您会看到我指定了 -T/-t/-b标志。
git svn init
这是我从现有的本地 git repo 中所做的：
# Create the project directory in subversion
$ /usr/bin/svn mkdir
https://example.com/svn/parent/trunk/project
-m "Make project directory."
Committed revision 200.
# Initialize git-svn, doesn't fetch anything yet
$ git svn init https://example.com/svn/
-T parent/trunk/project
-t parent/tags/project
-b parent/branches/project
--prefix=svn/
# Set authors so we get prettier authors
$ git config svn.authorsfile ../authors
# Now pull down the svn commits
$ git svn fetch
W: Ignoring error from SVN, ...
W: Do not be alarmed at the above message git-svn ...
This may take a while on large repositories
r200 = (guid) (refs/remotes/svn/trunk)
# We should now see our svn trunk setup under our svn remote
$ git branch -av
* master c3a7161 The latest git commit.
remotes/svn/trunk 3b7fed6 Make project directory.
# Now we want to take all of our local commits and
# rebase them on top of the new svn/trunk
$ git rebase svn/trunk
First, rewinding head to replay your work on top of it...
Applying: First git commit
Applying: The latest git commit
# Now we should see our local commits applied
# on top of svn/trunk
$ git lg
* 52b7977 (HEAD, master) The latest git commit
* a34e162 First git commit
* 3b7fed6 (svn/trunk) Make project directory.
# Everything is cool, push it back to svn
$ git svn dcommit
Committing to https://example.com/svn/parent/trunk/project

–prefix=svn
我最近特别喜欢的一个标志git svn clone是--prefix=svn/.
这将为远程 Subversion 分支、标签和主干的所有跟踪分支添加 svn/ 前缀，使其看起来很像常规 git 遥控器使用的通常的 origin/ 习惯用法。
使用带有前缀的跟踪分支，您还可以将它们用作本地分支名称，例如：
# Name your copy of svn/trunk "trunk" instead of "master"
$ git checkout -b trunk master
Switched to a new branch 'trunk'
$ git branch -d master
Deleted branch master (was 33c3136).
$ git branch -av
* trunk 33c3136 Latest svn commit
* remotes/svn/trunk 33c3136 Latest svn commit
然后，如果您有其他要跟踪的分支：
$ git checkout -b featurea svn/featurea
