No. Your best bet would be to set up a mirror of the svn repository in a dedicated git repository. 

<pre><code>git svn clone -s http://subversion.example.com/ mysvnclone
cd mysvnclone
git remote add origin git@example.com:project.git
git push origin master
</code></pre>

Then you can add the git repository as a submodule to the original project

<pre><code>cd /path/to/gitproject
git submodule add git://example.com/project.git -- svn-project
git add svn-project
git commit -m "Add submodule"
</code></pre>

There is one conceptual difference between svn:externals and git submodule that may trip you up if you approach this from a subversion point of view. The git submodule is pegged to the revision that you give it. If "upstream" changes, then you have to update your submodule's reference. 

So when we resync with the upstream subversion:

<pre><code>cd /path/to/mysvnclone
git svn rebase
git push
</code></pre>

... the git project will still use the original revision that we committed earlier. To update to the svn HEAD, you would have to use

<pre><code>cd /path/to/gitproject/svn-project
git checkout master
git pull
cd ..
git add svn-project
git commit -m"Update submodule"
</code></pre>

I just went through this. I'm doing something similar to rq, but slightly different.
I setup one of my servers to host these git clones of the svn repos I need. In my case I only want read-only versions, and need a bare repo on the server.

On the server I run:

<pre><code>GIT_DIR=&lt;projectname&gt;.git git init
cd &lt;projectname&gt;.git/
GIT_DIR=. git svn init svn://example.com/trunk
GIT_DIR=. git svn fetch
git gc
</code></pre>

This sets up my bare repo, then I have a cron script to update it:

<pre class="lang-py prettyprint-override"><code>#!/usr/bin/python

import os, glob

GIT_HOME='/var/www/git'

os.chdir(GIT_HOME)
os.environ['GIT_DIR']='.'
gits = glob.glob('*.git')
for git in gits:
 if not os.path.isdir(git):
 continue
 os.chdir(os.path.join(GIT_HOME, git))
 if not os.path.isdir('svn/git-svn'):
 #Not a git-svn repo
 continue

 #Pull in svn updates
 os.system('git svn fetch &amp;&amp; git gc --quiet')
 #fix-svn-refs.sh makes all the svn branches/tags pullable
 os.system('fix-svn-refs.sh')
 #Update the master branch
 os.system('git fetch . +svn/git-svn:master &amp;&amp; git gc --quiet')`
</code></pre>

This also requires fix-svn-refs.sh from <a href="http://www.shatow.net/fix-svn-refs.sh" rel="nofollow noreferrer">http://www.shatow.net/fix-svn-refs.sh</a> 
This was mostly inspired by: <a href="http://gsocblog.jsharpe.net/archives/12" rel="nofollow noreferrer">http://gsocblog.jsharpe.net/archives/12</a>

I'm not sure why the <code>git gc</code> is needed here, but I wasn't able to do a <code>git pull</code> without it.

So after all this you can then use git submodule following rq's instructions.

blocks|key|1645379|text|除了rq所说的之外，另一种方法是使用第三方“外部”项目(http://nopugs.com/ext-tutorial)，它更好地模拟了svn外部引用的工作方式。使用外部，您可以跟踪git或svn存储库，并且将您的更改向上推送到这些存储库看起来更容易。但是，它要求项目成员下载并安装单独的包。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1645380|我还没有使用子模块或外部变量；但是，我花了几个小时阅读了所有替代方案，看起来外部变量会更适合我的需求。在Jon+Loeliger+(http://oreilly.com/catalog/9780596520120)的“使用Git进行版本控制”的第15章中，有一个关于这些和其他自定义方法的很好的讨论，我强烈推荐。|1645381|entityMap|0|LINK|mutability|MUTABLE|url|http://nopugs.com/ext-tutorial|1|http://oreilly.com/catalog/9780596520120^0|S|U|0|0|1U|14|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

In addition to what rq said, another method would be to use the third-party "externals" project (<a href="http://nopugs.com/ext-tutorial" rel="nofollow noreferrer">http://nopugs.com/ext-tutorial</a>), which better mimics how svn external references work. With externals you can track either git or svn repositories, and it looks easier to push your changes upstream to those repos. However, it requires project members to download and install the separate package.

I haven't used submodules or externals yet; however, I've spent a few hours reading about all alternatives and it looks like externals will be a better fit for my needs. There is an excellent discussion about these and other custom methods in Chapter 15 of "Version Control with Git", by Jon Loeliger (<a href="http://oreilly.com/catalog/9780596520120" rel="nofollow noreferrer">http://oreilly.com/catalog/9780596520120</a>), which I strongly recommend.

blocks|key|1430529|text|嗯，有git-remote-testsvn，所以我猜大概是这样的|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1430530|git+submodule+add+testsvn::http://www.telegraphics.com.au/svn/bzquips/trunk/+\

Well, there is <code>git-remote-testsvn</code>, so I guess something like

<pre><code>git submodule add testsvn::http://www.telegraphics.com.au/svn/bzquips/trunk/ \
 module/bzquips
</code></pre>

should work. Does it?

Is there a way to add a Subversion repository as a Git submodule in my Git repository?

Something like:

<pre><code>git-svn submodule add https://svn.foo.com/svn/proj --stdlayout svn-project
</code></pre>

Where <code>https://svn.foo.com/svn/proj</code> points to a Subversion repository.

I know there is <code>git-svn</code> which allows one to interact with a Subversion repository. So I am thinking, maybe there is a way to checkout a Subversion repository with <code>git-svn</code> and then use it as a submodule.

Is it possible to have a Subversion repository as a Git submodule?
