$ref to another json schema not resolved

[abhijith-prabhakar]

Hi,

I have a $ref on a json file which references a json file in another directory.

title.json

 "currency" : {
    "$ref": "./common/currency_code.json"
 }

Swagger Codegen/parser fails to resolve this reference. Have created a sample application to demo the same. Tried with v2.2.1 and v2.2.2-SNAPSHOT version of the codegen.
