Duplikat #916. Ada solusinya

<strong i="6">@Getter</strong>
@Builder(toBuilder=true)
<strong i="7">@AllArgsConstructor</strong>
@NoArgsConstructor(access=AccessLevel.PRIVATE)
public class Entity {
    public static EntityBuilder builder() {
        return PROTOTYPE.toBuilder();
    }

    private static final Entity PROTOTYPE = new Entity();

    private String name;
    private boolean single = true;
}

Ini juga berfungsi

public class BuilderAnnotationTest {

    <strong i="6">@Test</strong>
    public void defalutValue() throws Exception {
        assertThat(new Entity().toBuilder().build().isSingle()).isTrue(); // note the "new" here
    }
}

<strong i="7">@Getter</strong>
@Builder(toBuilder = true)
class Entity{
    private String name;
    private boolean single = true;
}
