Why is Lombok @Builder not compatible with this constructor?

Question

I have this simple code:

@Data
@Builder
public class RegistrationInfo {

    private String mail;
    private String password;

    public RegistrationInfo(R         


        

Answer 1

Presumably, @Builder generates an all-args constructor iff there are no other constructors defined.

@Data
@Builder
@AllArgsConstructor(access = AccessLevel.PRIVATE)
class RegistrationInfo {

    private String mail;
    private String password;

    private RegistrationInfo(RegistrationInfo registrationInfo) {
        this(registrationInfo.mail, registrationInfo.password);
    }
}
