Mapstruct ignores @BeanMapping qualifiedByName

Question

I'm trying to use separated @AfterMaping / @BeforeMapping methods for 2 methods: toDto and toPartialDto , but MapStruct generates code, where all @AfterMaping / @BeforeMapping methods are used. I tried rework my abstract class to interface, but the problem remains.

    @BeanMapping(qualifiedByName = {"method1", "method2", "method3"})
    public abstract MyDto toDto(MyEntity entity);

    @Named("toPartialDto")
    @BeanMapping(ignoreByDefault = true, qualifiedByName = {"method3", "method4"})
    public abstract MyDto toPartialDto(MyEntity entity);

    @Named("method1")
    @BeforeMapping
    protected void setField1Data(@MappingTarget MyDto target, MyEntity entity) {
       //some code
    }

    @Named("method2")
    @AfterMapping
    protected void updateDto(@MappingTarget MyDto target, MyEntity entity) {
         //some code
    }

    @Named("method3")
    @AfterMapping
    protected void resolveOwn(@MappingTarget MyDto dto) {
       //some code
    }

    @Named("method4")
    @AfterMapping
    protected void mapPartial(@MappingTarget MyDto target, MyEntity entity) {
       //some code
    }

MapStruct doesn't ignore the qualifiers . When you define multiple qualifiers in BeanMapping#qualifiedByName MapStruct will try to match all of them. This is mostly meant for having a specific qualified class with qualified methods.
