[BUG] Can't override method build when 2 class also have @SuperBuilder()

[hoangdangduy]

Hi, Lombok team and people.

I use @SuperBuilder() in 2 class, I want override method build() of class child builder but it appear error "Abstract method 'build()' cannot be accessed directly" in super.build() in ClassChild

Version Lombok: 1.18.28
Version java: 17

ClassChild.java

@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
public class ClassChild extends ClassParent {
    private int age;

    public static ClassChildBuilder builder() {
        return new BuilderCustom();
    }

    public static class BuilderCustom extends ClassChildBuilder {

        public ClassChild build() {
            ClassChild classChild = super.build();
            return classChild;
        }

        @Override
        protected ClassChildBuilder self() {
            return this;
        }
    }
}

ClassParent.java

@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
@Data
public class ClassParent {
    private String name;
}

Main class

ClassChild classChild = ClassChild.builder().name("Tom").age(20).build();

How should I fix to override the build() method success?

What are you trying to do?

Manually implementing any of @SuperBuilder's code is tricky and you should really know what you are doing.
At least start with the delombok'ed code. Otherwise you'll be totally lost without the exact type parameters.

BTW: This is not a bug, this is a usage question better asked at StackOverflow.

I want override to process continue logic in build(), it will auto check, client don't need care about it when create object by builder.
