javax.ws.rs.ClientErrorException: HTTP 404 Not Found on Websphere 9 using Swagger

Question

I have a JAX-RS application running into Websphere 9.0 using Swagger.

We catch the stacktrace below. Does anyone have any idea on how to resolve?

Please add this dependency io.swagger:swagger-models:1.6.1. I guess you forgot to add this.

<dependency>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-models</artifactId>
    <version>1.6.1</version>
</dependency>

See if this works.
