Not able to link my javadocs with spring auto rest docs - spring-boot

Question

I am not getting how do you use JavaDocs, with Spring Auto Rest Docs. I can generate my java-docs locally by using STS, UI option. However,i am not sure how to generate java-docs using Spring Auto Rest Docs. I tried writing some plugin in POM. But the auto-description.adoc and many other doc are still empty.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.10.3</version>

<execution>

Basically I am not getting how to make Spring Auto Rest Docs use Java Docs to find Path Parameters. I can use mvn javadoc:javadoc command on terminal to create Javadocs whch are created in target/site/apidocs/ folder. But I still get No parameters in my auto-path-parameters.adoc
Here is the controller, I am using GraphQL so its different:
/**
* Query Controller Class
* #author shantanu
*
*/
#RestController
#RequestMapping(value="/graphql")
public class QueryController {
#Value("classpath:/graphql/actionItm.graphqls")
private Resource schemaResource;
private GraphQL graphQL;
#Autowired
#Qualifier("graphQLDate")
private GraphQLScalarType Date;
#Autowired
private AllActionItemsDataFetcher allActionItemsDataFetcher;
#Autowired
private ActionItemDataFetcher actionItemDataFetcher;
#Autowired
private PageActionItemDataFetcher pageActionItemDataFetcher;
#PostConstruct
public void loadSchema() throws IOException {
File schemaFile = schemaResource.getFile();
TypeDefinitionRegistry typeRegistry = new SchemaParser().parse(schemaFile);
RuntimeWiring wiring = buildRuntimeWiring();
GraphQLSchema schema = new SchemaGenerator().makeExecutableSchema(typeRegistry, wiring);
graphQL = GraphQL.newGraphQL(schema).build();
}
private RuntimeWiring buildRuntimeWiring() {
return RuntimeWiring.newRuntimeWiring()
.type("Query", typeWiring -> typeWiring
.dataFetcher("findAllActionItems", allActionItemsDataFetcher)
.dataFetcher("findActionItem", actionItemDataFetcher)
.dataFetcher("pageActionItems", pageActionItemDataFetcher))
.scalar(Date)
.build();
}
/**
* This
* #param query Description
* #return ResponseEntity responseEntity
*/
#PostMapping
public ResponseEntity query(#RequestBody String query) {
ExecutionResult result = graphQL.execute(query);
return ResponseEntity.ok(result.getData());
}
}
I am not getting where I am wrong, with the path-parameters. And only the .adoc files are generated with Spring Auto Rest Docs, and no JSON files.
