Not able to configure swagger with jax-rs webservices

Hi,

I had some experience with swagger and configured swagger very easily in one of my project which was in springboot.
But I need to configure swagger to a project where all the APIs/ webservices are written with jersey APIs (javax.ws.rs) (version 1.1.1)
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>

Link from where code is referred: https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-1.X-Project-Setup-1.5

Method I used in the current code:  Using a custom Application subclass

Error I am getting:

[WARNING[m] FAILED Jersey Spring Web Application: java.lang.NoSuchMethodError: org.reflections.util.ClasspathHelper.forPackage(Ljava/lang/String;[Ljava/lang/ClassLoader;)Ljava/util/Collection;

I tried upgrading the swagger-core version from 1.5.0 to 1.5.6 but no luck. 

I searched about this error and found out this google chat group : https://groups.google.com/g/swagger-swaggersocket/c/ZtNe0v4S6DA and followed all the steps. But still same issue.
Can someone please help?
