我要使用此命令从Google App引擎创建java lib
sudo python /var/www/html/google_appengine/endpointscfg.py get_client_lib java -bs gradle src.service.mobile_api.MobileApi
但出现错误
main__.ServerRequestException: HTTP 404 (Not Found) error when communicating with URL: https://webapis-discovery.appspot.com/_ah/api/discovery/v1/apis/generate/rest. Response: <html><head>
