I was trying to use lombok for my project. 

I have a class A:

```
@Data
@Builder
public class A {
    Integer a1;
}

```

and a class B:

```
@Data
public class B extends A {
    Integer b1;

    @Builder
    public B(Integer b1, Integer a1) {
        super(a1);
        this.b1 = b1;
    }
}

```

I am getting an error saying builder() in B cannot override builder() in A, as return type in BBuilder is not compatible with return type in ABuilder. 

Is there some way to do this using lombok? 
I do not want to write the complete builder for for B, unless I don't have any other option. 

PS: I have given explicit constructor for class B due to [Issue](https://reinhard.codes/2015/09/16/lomboks-builder-annotation-and-inheritance/).
I tried searching, but I could not find a good solution for the same.
