Using mapstruct to get inner object from outer object

I have an object that looks like this:

public class Aggregator {

private Header header;
private Second second;

}

And I want to map from Aggregator to Header but I can't use void methods Mapstruct version is 1.3

How can I achieve that goal?

Edit:

I'm trying to map the business entity "Aggregator" to the DTO entity "HeaderDTO"

I'm trying to achieve that by creating an abstract class with the annotation: @Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE) and the method: "public abstract HeaderDTO toDTO(Aggregator aggregator);"

@Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE)
public abstract class AggregatorMapper {


public abstract HeaderDTO toDTO(Aggregator aggregator);

}

MapStruct allows you to map the entire target object to a particular source reference.

e.g.

@Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE)
public abstract class AggregatorMapper {

    @Mapping(target = ".", source = "header"
    public abstract HeaderDTO toDTO(Aggregator aggregator);

}
