Unable to call a restful service using swagger codegen and saying unauthorized for basic auth

Hi Team,

Consuming a restful service using swagger codegen 2.0 But its failing the authentication.

"swagger": "2.0",
"info": {
"version": "2.1.0",
"title": "GeoES"

Schema does not have securityDefinitions:
basic:
type: basic
description: HTTP Basic Authentication.

So, I tried changing Apiclient authantications map and added manually credentials. But no luck.
HttpBasicAuth hba= new HttpBasicAuth();

	    hba.setUsername("*******");
        hba.setPassword("*******");
        authentications.put("basic", hba);
   authentications = Collections.unmodifiableMap(authentications);

I changed buildCall to allow but still It's not getting authenticated. Need Help !!
String authNames2[] = {"basic"};
updateParamsForAuth(authNames2, queryParams, headerParams);

Thank you

Start with the Swagger 2.0 definition and the generated Java ApiClient, focusing on buildCall and updateParamsForAuth. Reproduce the request with basic authentication configured, then verify that the generated call sends credentials and no longer receives an unauthorized response.
