Cloning git repository from svn repository, results in file-less, remote-branch-less git repo

Working SVN repo

I'm starting a git repo to interact with a svn repo. The svn repository is set and working fine, with a single commit of a basic README file in it.

Checking it out works fine:

tchalvak:~/test/svn-test$ 
svn checkout --username=myUsernameHere http://www.url.to/project/here/charityweb/
A    charityweb/README
Checked out revision 1.

Failed git-svn clone of svn repo

When I try to clone the rep开发者_如何学Pythonository in git, the first step shows no errors...

tchalvak:~/test$ 
git svn clone -s --username=myUserNameHere http://www.url.to/project/here/charityweb/
Initialized empty Git repository in /home/tchalvak/test/charityweb/.git/
Authentication realm: <http://www.url.to/project/here:80> Charity Web
Password for 'myUserNameHere': 

...but results in a useless folder, containing no files, no branches, and no commits:

tchalvak:~/test$ ls
charityweb
tchalvak:~/test$ cd charityweb/
tchalvak:~/test/charityweb$ ls
tchalvak:~/test/charityweb$ ls -al

nothing to commit (create/copy files and use "git add" to track)

fatal: Needed a single revision

tchalvak:~/test/charityweb$ git log
fatal: bad default revision 'HEAD'

How do I get something I can commit back to? I expect I'm doing something wrong in this process, but what?

You used the -s option to git svn clone, but from your example, it doesn't appear that your Subversion repository is using the standard layout (i.e., trunk, branches, and tags directories at the repository root).

If that's the case, clone without -s.
