Plugin won't recognize @Named class

I was trying to implement this pattern from documentation:

As for mapper itself, it is working fine and dandy. The plugin, however, seems to have problem with finding the annotated class which contains annotated mapping method. Error description is provided:

"Unknown @ Named reference 'TranslationMapper' ".

Reference for "TranslationsToString" is found properly.

@Mapper(uses = TranslationMapper.class)
public interface PrimaryClassMapper {
    @Mapping(source = "primary.id", target = "id")
    @Mapping(
            source = "primary.translatedNames",
            target = "name",
            qualifiedByName = {"TranslationMapper", "TranslationsToString"})
    SecondaryClass toSecondaryClass(PrimaryClass primary, @Context Language targetLanguage);
}

@Named("TranslationMapper")
public class TranslationMapper {
    @Named("TranslationsToString")
    public String resolveTranslatedText(
            List<TranslationDto> translations, @Context Language targetLanguage) {
        //some fancy logic
    }
}

首先使用 issue 中的 PrimaryClassMapper 和 TranslationMapper 範例重現此警告，重點關注類別層級和方法層級的 @Named 註解以及 qualifiedByName 參照。完成的標準是：plugin 能夠識別類別層級的 "TranslationMapper" 參照，而不將其回報為未知，同時仍能解析 "TranslationsToString"。
