The SVN URL string must be exactly the same as the one recorded in the log.

git-svn-id: svn://localhost/xxx/trunk@2977 c27b2ed6-37b1-4487-878e-468635907f87

If the SVN URL is different, you will get the following:

Rebuilding .git/svn/refs/remotes/git-svn/.rev_map.c27b2ed6-37b1-4487-878e-468635907f87 ...

Last fetched revision of refs/remotes/git-svn was r2977, but we are about to fetch: r1!

If you want to change the SVN URL, e.g.  "svn://localhost/xxx/trunk" to "svn://192.168.1.1/xxxx/trunk", you can do "git commit --amend" to alter the last commit's git-svn-id from

git-svn-id: svn://localhost/xxx/trunk@2977 c27b2ed6-37b1-4487-878e-468635907f87

to

git-svn-id: svn://192.168.1.1/xxx/trunk@2977 c27b2ed6-37b1-4487-878e-468635907f87

And set the git-svn to the new commit and run "git svn fetch"
