So you can write down something like this: @KotlinBuilder data class Person(var firstName: String, var lastName: String, var phoneNumber: String, var birthdate: LocalDate) The main idea is generating a builder for each data class and pass these builders to mapstruct via a custom BuilderProvider. The "problem" is that MapStruct resolves magic() as a mapping method and also applies it when mapping the "foo" field: (Here 'UD2' refers to the data table column for the product dimension).
