我需要将客户从 SVN 迁移到 Git，所以我想首先在公共 SVN 存储库上尝试 svn2git。
我找到了几个公共仓库，例如https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco和http://svn.apache.org/repos/asf/spamassassin。没有问题svn co，但是当我尝试 svn2git 时，我得到以下问题：
D:\Documents\work\svn2git\apache>svn2git http://svn.apache.org/repos/asf/spamassassin
Initialized empty Git repository in D:/Documents/work/svn2git/apache/.git/
Using higher level of URL: http://svn.apache.org/repos/asf/spamassassin => http://svn.apache.org/repos/asf

This may take a while on large repositories

为什么会发生？是权限问题吗？
