Steps to reproduce the problem

@Mapper
public abstract class ExampleMapper {
    @Mapping(target = "name", source = ".", qualifiedByName = "getFromFlatObject")
    public abstract ObjectWithFlatProperties map(ObjectWithNestedProperties objectA);

    @InheritInverseConfiguration
    @Mapping(target = "nestedObject.nestedName", source = "name")
    public abstract ObjectWithNestedProperties map(ObjectWithFlatProperties objectB);

    @Named("getFromFlatObject")
    protected String mapFromFlatObject(final ObjectWithNestedProperties object) {
        // Some logic here
        return object.getNestedObject().getNestedName();
    }
}
@Value
public class NestedObject {
    String nestedName;
}
@Value
public class ObjectWithFlatProperties {
    String name;
}
@Value
public class ObjectWithNestedProperties {
    NestedObject nestedObject;
}
