Add method for lists with lombok

like below fixes the issue 1) I couldn't find a ticket for it, and, based on the comment on the other answer, I filed one: https://github.com/rzwitserloot/lombok/issues/1905 So let's see :)
2) For a single collection, it seems that @Delegate could do the job:
code :
interface CollectionAdders<E> {
  boolean add(E e);
  boolean addAll(Collection<? extends E> c);

interface ListGetters<E> {
  E get(int index);

class Foo {
  @Delegate(types={CollectionAdders.class, ListGetters.class})
  List<String> names = new ArrayList<>();
Foo#add(E e)
Foo#addAll(Collection<? extends E> c)

Foo#get(int index)

Custom Lombok Extensions Require Lombok Package?

Custom Lombok Extensions Require Lombok Package?

I wish this helpful for you Due to classloader issues in Eclipse, Lombok patches the Equinox classloader to load classes in the lombok package from a different location. This is hardcoded. So your extension must also be in the lombok package, or you need to modify the code in EclipsePatcher to also include your own package.

lombok @Builder on method

lombok @Builder on method

help you fix your problem I want to use fluent Api to reduce the parameter list of a method. I dont want to create a constructor for this, so I annote the method with Lombok-@Builder: , This is how you use the default Builder syntax.
code :
public static void test(User user, Item item){
    // ...

public void buildTestExample(){
            .user(new User())
            .item(new Item())
@Builder(builderMethodName = "buildTest")
public static void test(User bar, Item item){
    // ...

public void buildTestExample(){
            .user(new User())
            .item(new Item())
@Builder(builderMethodName = "buildFoo")
public static String foo(String param1, String param2){
    return "foo" + param1 + param2;

@Builder(builderMethodName = "buildBar")
public static String bar(String param1, String param2){
    return "bar" + param1 + param2;

public void test(){


Lombok's lombok.copyableAnnotations not working with Jackson annotations

Lombok's lombok.copyableAnnotations not working with Jackson annotations

seems to work fine I'm trying to make use of Lombok's new copyableAnnotations feature in order to have Jackson annotations like @JsonIgnore and @JsonValue copied to generated getter/wither methods. This blog seems to suggest this should work: https://www.thecuriousdev.org/lombok-builder-with-jackson/. However, when I try this I simply get "error: annotation type not applicable to this kind of declaration" (pointing to my value field). Why is this not working and how do I make it work? Perhaps I'm misunderstanding how this feature is supposed to work. I'm using lombok 1.18.8. ,
Why is this not working […] ?
code :
    private Long value;

    public Long getValue() {
        return value;
    private Long value;

may help you . Edit: Try making your inner ProcessorLombokBO class static. You can't use Builder on an inner non-static class, as the compile error at your example suggests in my IDE (Eclipse)
