Research direction

The reported example is in guide-for-java-devs.pdf and spans Wiki.java, WikiDbService.java, and WikiDbServiceImpl.java. Reproduce the compilation failure with Lombok's @AllArgsConstructor, then trace the Java code-generation path involved. Done means the example compiles with the generated two-argument constructor, with a regression test if the repository has a suitable location.

Written by the indexing model from the issue text.

Description

This is a code example in the book (guide-for-java-devs.pdf), and I made a piece of changes.

  1. Wiki.java corresponds with the database table:
@AllArgsConstructor
public class Wiki {
    public Long id;
    public String name;
}
  1. WikiDbService.java
@ProxyGen
public interface WikiDbService {

    @Fluent
    WikiDbService fetchAll(Handler<AsyncResult<JsonArray>> resultHandler);

    @GenIgnore
    static WikiDbService create(JDBCClient dbClient, Handler<AsyncResult<WikiDbService>> readyHandler) {
        return new WikiDbServiceImpl(dbClient, readyHandler);
    }

    @GenIgnore
    static WikiDbService createProxy(Vertx vertx, String address) {
        return new WikiDbServiceVertxEBProxy(vertx, address);
    }
}
  1. WikiDbServiceImpl.java
    @Override
    public WikiDbService fetchAll(Handler<AsyncResult<JsonArray>> resultHandler) {
        dbClient.query(FETCH_ALL_SQL, queryAr -> {
            if (queryAr.failed()) {
                resultHandler.handle(Future.failedFuture(queryAr.cause()));
                return;
            }

            ResultSet resultSet = queryAr.result();
            List<Wiki> wikiList = resultSet.getResults().stream()
                .map(r -> new Wiki(r.getLong(0), r.getString(1)))
                .collect(Collectors.toList());

            resultHandler.handle(Future.succeededFuture(new JsonArray(new Gson().toJson(wikiList))));
        });

        return this;
    }

Finally, I got a compilation error:

it means that there no suitable constructor for Wiki class with 2 arguments ....

But If I generate the constructor:

public class Wiki {
    public Long id;
    public String name;

    public Wiki(Long id, String name) {
        this.id = id;
        this.name = name;
    }
}

It works.

So I think it's not compatible with lombok ...
