在gitlab上創建了一個project, 然後在linux 裡 git svn clone project_svn_url, 最後成功push到gitlab上。
但是，在gitlab上把這個project 刪除了， 再創建了一個同名project,
又在linux 上重做git svn clone， 再也得獲取不了代碼，只得到一個空目錄， 已經確定svn 上有代碼的.
不知怎麼回事. 求救各位，謝謝

admin$ git svn clone http://project_svn_url --no-metadata --authors-file=author.txt
Initialized empty Git repository in /myworkspath/project/.git/

完了之後只是個空目錄
