I have a lot of DTO interfaces which I’m using with Immutables like this one:

@Value.Immutable
public interface UserTeamDto extends BaseRelationshipDto {

I’m also using them with Mapstruct to transform those DTOs into Entities (and vice-versa) using some generic mapper classes, and its working well:

D toParentDto(E pParentEntity, @Context MC pMapperContext);

But I have multiple cases (Many to Many relatioships) where I need to use @Context callback events and I need to pass the generated Builder to the mapping method.

    @AfterMapping
    public void processChildDto(@MappingTarget ImmutableUserDto.Builder pParentEntity) {
   
    ....
    }

But I would like to find a way to do this generically too.

One thing that I thought was to make the Build to implement a common interface as well as I do in the origin interface, but I couldn’t find a way to setup this on Immutables for all DTO interfaces that extends BaseRelationshipDto.

Is there any way to do this ?
