download-commands插件配置

[download]               
  scheme = ssh
  scheme = http　　　　　 #认证http下载
  scheme = anon_http   　#匿名http下载
  scheme = anon_git
  scheme = repo_download

If download.scheme is not specified, SSH, HTTP and Anonymous HTTP downloads are allowed.

gerrit配置认证方式为HTTP时，认证过程由代理服务器完成，如果没有设置HTTP Password 的话，那么就无法通过HTTP的url来clone和push代码。
