Почему Map Struct иногда генерирует неправильный Mapper, и как я могу ее исправить? ⇐ JAVA

[Anonymous]

Я использую Java 8, Spring Boot 2.3.4. РЕЛИЗА ВЕРСИЯ, MAVEN в качестве инструмента сборки и IntelliJ в качестве моего IDE. Class = "Lang-Java PrettyPrint-Override">@Mapper(componentModel = "spring", nullValuePropertyMappingStrategy = NullValuePropertyMappingStrategy.IGNORE)
public interface MapStructVehicleMapper {
Vehicle toVehicle(VehicleMasterDto dto);
void updateVehicleFromDto(@MappingTarget Vehicle vehicle, VehicleDetailDto vehicleDetailDto);
}
< /code>
Приведено ниже зависимости, которые я использовал.

Проблема, с которой я сталкиваюсь, заключается в том, что когда IMP Mapstruct генерирует во время компиляции, иногда она генерирует правильную реализацию, но иногда это не так.@Generated(

Иногда он генерирует следующий карт, который неверный: < /p>

@Override
public void updateVehicleFromDto(Vehicle vehicle, VehicleDetailDto vehicleDetailDto) {

Из -за этого случайного поведения я не могу доверять структуре карты в нашей производственной среде. Таким образом, мне пришлось создать ручную карту. Может ли кто -нибудь помочь мне понять основную проблему здесь?
