Ошибка 404 при попытке доступа к {API} /swagger.json - джерси 1.x swagger-core 1.5.8

Question

Я пытаюсь интегрировать Swagger (версия 1.5.8) в существующий REST API, который использует Джерси 1.19. Я следовал документации для реализации swagger в приложении jersey 1.x, но, что бы я ни пытался, конечная точка (localhost: 8080 / swagger. json) всегда возвращает 404.

Ресурсы находятся в my.namespace.webservice . Также нигде не определен @ApplicationPath, поэтому, если я правильно понимаю, я смогу получить чванство. json, вызвав localhost: 8080 / swagger. json.

Любые указатели в правильном направлении были бы очень полезны!
