Generate OpenAPI YAML File from Swagger Annotations - gradle

I have a java class with the openapi documented using swagger annotations as below. I want to generate the JSON file for this documentation using gradle, but I am unable to do so. I have tried using the OpenAPI Generator Gradle Plugin but I believe this plugin works the other way around. How can I generate the JSON file from the swagger annotations?

Validate Swagger OpenAPI Specification yaml

I have a Spring Boot application that contains the OpenAPI .yaml specification file in the resources folder and using the openapi-generator-maven-plugin, building the project it generates the API interfaces and then can be used as a maven artifact in another project to implement those APIs.
Currently, I am validating the specification file locally using the Swagger CLI validate command through the terminal.
Is there a way to validate the specification.yaml file when building the project using another plugin or something like that?
If no, is there any dependency I can use to validate the .yaml file while running the project?

OpenApi Swagger generate Java RestTemplate client

I'm using Openapi 3 to generate java http client.
In my maven plugin configuration, I'm using "resttemplate" :
So I was expecting as a result Spring RestTemplate classes to make HTTP calls.
But in generated sources, I got ApiClient class to handle HTTP calls. ApiClient comes from Jersey library. There's no mention about Spring RestTemplate classes :
Is this normal ?
From the documentation at this link: https://github.com/OpenAPITools/openapi-generator/blob/master/docs/generators/spring.md
Search for the library config option in the big table, and you'll see that the two choices for the library config option are spring-boot or spring-cloud. You're using resttemplate, which is not valid.
(You're using version 5.1.0 of the generator, I'm using 5.0.0, but I'm pretty sure the link I provided applies to both.)

Generate api documentation without creating rest with swagger2

I'm new to spring and swagger so I have some difficulties with generating API documentation using swagger. I've done API documentation at http://localhost:8080/swagger-ui.html, but I have to export generated API documentation to the other website. Is there a way to generate just json or yml file without displaying documentation at swagger-ui.html?

Adding Swagger API Documentation to Maven Site

I have a Spring Boot project and I'm using swagger to test and document the API. The project also contains a bunch of classes that are used as libraries and I'm using scala docs to document those. Is there a way to unify API docs (from swagger) and Scala Docs as I'm hosting the docs using maven site plugin.

how can i publish swagger doc generated by springfox as part of the build process

We are using springfox to generate swagger docs for our springboot application at runtime. We would like to publish these somewhere as part of our jenkins pipeline. Is there a way to generate these static docs as part of the build that we can then export in the pipeline?
