java - Spring @Builder annotation is not providing builder() method - Stack Overflow

I am writing some custom exception methods with a custom Response class. This is my Response Class

package com.mahadi.InventoryManagementSystem.dto;

import java.time.LocalDateTime;
import java.util.List;

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.mahadi.InventoryManagementSystem.enums.UserRole;

import lombok.Builder;
import lombok.Data;

@Data
@Builder
@JsonInclude(content = Include.NON_NULL)

public class Response {

   // generic
   private int status;
   private String message;
   
   // for login
   private String token;
   private String expirationTime;
   private UserRole role;
   
   // for pagination
   private Integer totalPages;
   private Long totalElement;
   
   // data output optional
   private UserDTO user;
   private List<UserDTO> userList;

This is my Global Exception handler class

package com.mahadi.InventoryManagementSystem.exceptions;

import org.springframework.http.HttpStatus;
import org.springframework.http.HttpStatusCode;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;

import com.mahadi.InventoryManagementSystem.dto.Response;

@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(Exception.class)
    public ResponseEntity<Response> handleAllExceptions(Exception exception) {
        Response response = Response.builder()
                .status(HttpStatus.INTERNAL_SERVER_ERROR.value()) // or other status code
                .message(exception.getMessage()) // exception message           
                .build();

        return new ResponseEntity<>(response, HttpStatus.INTERNAL_SERVER_ERROR);
    }
    
}

Now look at the screenshot. Here the builder method is not responding, but I added the @Builder annotation in the Response class. I failed to fix it. I need your suggestion. I am using JDK 17 with spring boot 3.0.0

• Did you look at the class files that Lombok generated? – Mr. Polywhirl Commented Jan 30 at 17:46
• @Mr.Polywhirl, I don't get your question – Mahadi Hasan Commented Jan 30 at 18:01
• 1 In an IDE like JetBrains IntelliJ, you can view the decompiled class object. – Mr. Polywhirl Commented Jan 31 at 0:55

If you have a custom constructor, Lombok might not generate the builder method unless you specify @Builder on the constructor itself. Try rebuilding the Project: After making changes, clean and rebuild your project to ensure that Lombok's annotations are processed correctly.
