如何将大型SVN存储库转换为Git？

Question

I'm trying to convert several SVN repositories to Git. Two have gone smoothly. When I try to convert the next, large-ish one, I get errors from git svn clone . First a bunch of:

W: Refspec glob conflict (ref: refs/remotes/origin/tags/Something-Perl):
expected path: something/trunk/tags/Something-Perl
    real path: something/tags/Something-Perl

for various "something." Then one:

Initializing parent: refs/remotes/origin/TheName@27584
Use of uninitialized value $args[1] in join or string at /usr/share/perl5/vendor_perl/Git.pm line 1635.
Use of uninitialized value $_[2] in exec at /usr/share/perl5/vendor_perl/Git.pm line 1661.
fatal: Not a valid object name
ls-tree -z  ./: command returned error: 128

Digging, I find line 1635 is

return wantarray ? ($fh, join(' ', $cmd, @args)) : $fh;

Google found a few instances of errors in Git.pm or SVN.pm but not this one. (For reference, I'm using git version 2.19.1 on Linux.)

I really only want two of the directories in that repo so I tried to follow Migrating a large SVN repo to git but I end up with an empty Git repo:

[MyNewRepo]$ git status
On branch master

No commits yet

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

Any thoughts?

If you are only exporting to git you are better of using the KDE svn2git. It's much faster and allows you to create annotated tags. https://github.com/svn-all-fast-export/svn2git
