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 示例重现该警告，重点关注类级别和方法级别的 @Named 注解以及 qualifiedByName 引用。完成的标准是：插件能够识别类级别的 "TranslationMapper" 引用而不将其报告为未知，同时仍能解析 "TranslationsToString"。
