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; [WARNING[m] FAILED
