Asciidoctor Snippets отсутствует в Maven

Когда я запускаю тестовый пример, запросы и ответы типа adoc будут создаваться и отображаться в формате JSON в каталоге сгенерированных фрагментов. когда я запускаю эту команду mvn mvn clean package для создания индекса типа jar и HTML в сгенерированных документах, возникает следующее предупреждение

когда я открываю index.html через браузер, в ответ вместо результата JSON отображается Unresolved directive in index.adoc.

= Nafaz Benzema Getting Started With Spring REST Docs

    This is an example output for a service running at http://localhost:9090:
    
==GET API Example

.request
include::{snippets}/getAllProduct/http-request.adoc[]

.response
include::{snippets}/getAllProduct/http-response.adoc[]

As you can see the format is very simple, and in fact you always get the same message.
