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

You can either add an @AllArgsConstructor annotation, because

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

(Quotting @Andrew Tobilko)

Or set an attribute to @Builder : @Builder(toBuilder = true) This gives you the functionality of a copy constructor.

@Builder(toBuilder = true)
class Foo {
    // fields, etc
}

Foo foo = getReferenceToFooInstance();
Foo copy = foo.toBuilder().build();
