ModelMapper: mix implicit and explicit mapping?

Question

To write down the minimum required code, I try to let ModelMapper generate its implicit mapping and write only explicit property mappings for those properties that it could not auto-arm.

If I can let ModelMapper generate an implicit mapping using:

modelMapper.createTypeMap(SourceType.class, DestType.class);

he complains about setSomeIdhaving several possible mappings. Then I tried to fix this using:

modelMapper.addMappings(new PropertyMap<SourceType, DestType>() {
    protected void configure() {
        map().setSomeId(source.getProperty().getWeirdID());
    }
});

However, I found that ModelMapper is still complaining, because in fact the exception throws itself at createTypeMap, so it has no way to reach my custom match code.

If I invert both operators, I get an error message:

java.lang.IllegalStateException: TypeMap SourceType DestType

createTypeMap, ModelMapper DestType (, createTypeMap).

ModelMapper.createTypeMap ModelMapper.addMappings (). ( ) a TypeMap, PropertyMap.

    TypeMap<RateDTO, Rate> rateDTORateTypeMap = modelMapper.getTypeMap(RateDTO.class, Rate.class);
    if(rateDTORateTypeMap == null) {
        rateDTORateTypeMap = modelMapper.createTypeMap(RateDTO.class, Rate.class);
    }
    rateDTORateTypeMap.setProvider(request -> {
        RateDTO source = RateDTO.class.cast(request.getSource());
        CurrencyAndAmount price = new CurrencyAndAmount(source.getPrice().getCurrencyCode(), source.getPrice().getAmount());
        return new Rate(price, source.getPaymentDate(), source.getPaymentId());
    });
