Ignore fields by Suffix or type

Use case

Hello,

I am using Mapstruct with Avro, and the generated class has builder fields that Mapstruct is trying to map.

Because of that, in every mapper, I have to ignore those fields:

import com.my.event.MyEventMapper;
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;

@Mapper(
    config = EventConfig.class)
public interface AvroMyEventMapper {

  @Override
  @Mapping(target = "metadata", source = "data")
  @Mapping(target = "eventPayload", source="data")
  @Mapping(target = "snapshotPayload", source = "booking")
  @Mapping(target = "snapshotPayloadBuilder", ignore = true)
  @Mapping(target = "metadataBuilder", ignore = true)
  @Mapping(target = "eventPayloadBuilder", ignore = true)
  AvroRefundRequestedEvent map(Data data);
}

Do you know which trick I can implement to avoid that ?
I tried with SPI by trying to ignore type which ends with Builder but without success for now, is SPI would it be the good way to do it ?

Thank you !

Start with the MapStruct SPI approach described in the issue and the generated Avro mapper example. Investigate whether fields can be ignored by a suffix or type without repeating the three @Mapping(ignore = true) entries. Done means the shown mapper can exclude the generated Builder fields through supported configuration.
