如何在Go中禁用凭据提示以进行git clone？

Question

I'm trying to run the equivalent of git clone in Go but I want to exit out of the command if prompted for input from stdin (ex: authentication if an ssh key hasn't been set up in the remote repository). Is there a way to do this? Right now it will simply block on input.

UPDATE: special git solution.

Since v 2.3 git supports environment setting GIT_TERMINAL_PROMPT=0 which says not to ask for credentials but fail.

func main() {
    cmd := exec.Command("git", "clone", "https://github.com/some/non-existing-repo")
    os.Setenv("GIT_SSH_COMMAND", "ssh -oBatchMode=yes")  // 
    cmd.Env = append(os.Environ(), "GIT_TERMINAL_PROMPT=1", "GIT_SSH_COMMAND='ssh -oBatchMode=yes'")

    cmd.Stdout = os.Stdout
    err := cmd.Run()
    if err != nil {
        log.Println("Error: ", err)
    }
}
