Mirror is not a valid options

Hello all dears ,
Today I did signup in forums and I’m a newbie in GitLab.
I want clone a git with composer but I got this error: “–miror is not a valid options”
Where is the problem? With Composer or Git?
Here is the error:

  Failed to execute git clone --mirror "  
  s/news-base.git" "C:/Users/MyUser/AppData/Local/Composer/vcs/http---192.16  
  fatal: "--mirror" is not a valid option  

Thanks in advance.

I have just hit this problem. Did you resolve it ?
