git svn clone無法取得程式碼

Question

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/
...
W: Do not be alarmed at the above message git-svn is just searching aggressively for old history.
This may take a while on large repositories

    A    test
W: +empty_dir: instance_manager
W: +empty_dir: meta_server

    A    instance_manager/APScheduler-3.0.4/apscheduler/executors/pool.py
    A    instance_manager/APScheduler-3.0.4/apscheduler/executors/base.py
...

完了之後只是個空目錄

admin $ ll project/
total 0
drwxr-xr-x   3 admin  staff  102  1 13 21:53 ./
drwxr-xr-x  10 admin  staff  340  1 13 21:53 ../
drwxr-xr-x  12 admin  staff  408  1 13 21:54 .git/  

Answer 1

最後問題是有個user沒有在autor.txt中設置，git svn clone 退出了，但這個提示訊息不容易注意到

git-svn 克隆
