ModelMapper java 8 mappings by lambda

Question

I have a problem with Getting started example from ModelMapper with Java8. They show that using their library you can define mappigs like

ModelMapper modelMapper = new ModelMapper();

modelMapper.addMappings(mapper -> {
    mapper.map(src -> src.getBillingAddress().getStreet(), Destination::setBillingStreet);
    mapper.map(src -> src.getBillingAddress().getCity(), Destination::setBillingCity);
});

what obviously doesn't work and what's more cannot work since ModelMapper is not generic (so you cannot infer src and dst types)

public class ModelMapper {
    ...
}

and what's more map() method does not accept functional interface but PropertyMap object

public abstract class PropertyMap<S, D> {
    ...
}

I've checked ModelMapper Github page to see examples but it seems that they are using Java6/7 approach everywhere... :) Why then there is such example for Java8 in Getting started if it is not working and has no chance to work?

Have you ever investigated this? What am I doing wrong?

I use ModelMapper 2.3.0

EDIT

it should be

ModelMapper modelMapper = new ModelMapper();
modelMapper.createTypeMap(Order.class, OrderDTO.class)
   .addMappings(mapper -> {
       mapper.map(src -> src.getBillingAddress().getStreet(), OrderDTO::setBillingStreet);
       mapper.map(src -> src.getBillingAddress().getCity(), OrderDTO::setBillingCity);
});

It seems that in official tutorial they named modelMapper TypeMap instance not ModelMapper :)
