java.lang.NoSuchMethodError (SwaggerDeserializer)

[neeasthana]

Hello I am having trouble running the sample code provided in the readme. I have included all dependencies and imported the proper libraries. Is there a reason I am getting this error for the Pet Store example. Any insight would be appreciated.

The following line produces a java.lang.NoSuchMethodError:

package ibm;

import io.swagger.parser.SwaggerParser;
import io.swagger.models.Swagger;

public class Test {

    public static void main(String[] args) {
        Swagger swagger = new SwaggerParser().read("http://petstore.swagger.io/v2/swagger.json");
        System.out.println(swagger.toString());
    }

}

Stack Trace:

Please re-pull from master, you'll probably have to exclude swagger-core dependencies from springfox as they're out of date with the parser version you're using.
