git-svn error when cloning apache repo

I'm trying to clone the Apache Ivy repo and got this error. What does the "Using higher level of URL" mean? Also, of course, what does the error message mean?

$ git svn clone https://svn.apache.org/repos/asf/incubator/ivy/core/ ivy-core -T trunk -b branches -t tags

Any thoughts are appreciated.

Thanks.

I'm fairly sure this is where it went wrong. Try editing .git/config and putting your original URL in the source URL, and re-try the fetch.

Hmm... thanks, but didn't work. The repo didn't look right to begin with. The HEAD pointed to refs/heads/master as usual, but there was nothing in refs/heads at all.

I also tried: git svn clone https://svn.apache.org/repos/asf/ ivy-core -s --prefix=incubator/ivy/core/

And got no errors, but there wasn't any working tree in ivy-core afterwards. Then I tried 'git svn rebase':

fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree. Use '--' to separate paths from revisions fatal: Needed a single revision invalid upstream

Due to the same "nothing in refs/heads" situation. Also there is this 23M file .git/svn/incubator/ivy/core/trunk/.rev_db.13f79535-47bb-0310-9956-ffa450edef6 that contains all 0's.

The part before "I also tried..." was with git 1.5.3. "I also tried..." was with git 1.5.3.1.112.gb7a2 as of last night.

Cheers.
