Lombok @Builder error

I'm getting this error:

java: cannot find symbol
  symbol:   method builder()

java: cannot find symbol
  symbol:   method builder()

when using the .builder() method on an object that I previously marked with the

@Builder

@Builder

annotation

😱 thats truly a disaster show the code where ur trying to use builder

IamMax420OP•2w ago

Ikr I'm going insane atp there's always some fucking bug everyday 😿 so here's where I'm using it

    private Book mapToBook(BookDto bookDto) {
        if(!BookServiceUtils.isBookDtoValid(bookDto)) {
            return null;
        }

        return Book.builder()
                .author(bookDto.getAuthor())
                .title(bookDto.getTitle())
                .category(bookDto.getCategory())
                .pages(bookDto.getPages())
                .quantity(bookDto.getQuantity())
                .build();
    }

    private Book mapToBook(BookDto bookDto) {
        if(!BookServiceUtils.isBookDtoValid(bookDto)) {
            return null;
        }

        return Book.builder()
                .author(bookDto.getAuthor())
                .title(bookDto.getTitle())
                .category(bookDto.getCategory())
                .pages(bookDto.getPages())
                .quantity(bookDto.getQuantity())
                .build();
    }

ayylmao123xdd•2w ago

do u still have the old dependency setup for lombok

IamMax420OP•2w ago

and here's the Book entity

@Entity
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@Builder
@Table(name = "book", uniqueConstraints = {
        @UniqueConstraint(columnNames = "title")
})
public class Book {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(nullable = false)
    private Long id;
    @Column(nullable = false)
    private String author;
    @Column(nullable = false)
    private String title;
    @Column(nullable = false)
    private String category;
    @Column(nullable = false)
    private Integer pages;
    @Column(nullable = false)
    private Integer quantity;
}

@Entity
@NoArgsConstructor

@Builder
@Table(name = "book", uniqueConstraints = {
        @UniqueConstraint(columnNames = "title")
})
public class Book {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(nullable = false)
    private Long id;
    @Column(nullable = false)
    private String author;
    @Column(nullable = false)
    private String title;
    @Column(nullable = false)
    private String category;
    @Column(nullable = false)
    private Integer pages;
    @Column(nullable = false)
    private Integer quantity;
}

oops wrong message when u format code do 3 ticks and type java at the beginning of the message so it has color look

@Entity
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@Builder
@Table(name = "book", uniqueConstraints = {
        @UniqueConstraint(columnNames = "title")
})
public class Book {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(nullable = false)
    private Long id;
    @Column(nullable = false)
    private String author;
    @Column(nullable = false)
    private String title;
    @Column(nullable = false)
    private String category;
    @Column(nullable = false)
    private Integer pages;
    @Column(nullable = false)
    private Integer quantity;
}

@Entity
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@Builder
@Table(name = "book", uniqueConstraints = {
        @UniqueConstraint(columnNames = "title")
})
public class Book {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(nullable = false)
    private Long id;
    @Column(nullable = false)
    private String author;
    @Column(nullable = false)
    private String title;
    @Column(nullable = false)
    private String category;
    @Column(nullable = false)
    private Integer pages;
    @Column(nullable = false)
    private Integer quantity;
}

anyway you probably dont need to specify nullable false on each field instead you could do validation on the fields when you are creating the entity next show the pom file with lombok setup

JavaBot•2w ago

Please format your code & make it more readable. For the java programming language, it should look like this:

```java public class Main { public static void main(String[] args){ System.out.println("Hello World!"); } ```

• These are backticks, not quotes.

IamMax420OP•2w ago

for some reason it's not letting me post the pom.xml file I'm getting some discord error

ayylmao123xdd•2w ago

o btw you can just do

@Column(unique = true)

@Column(unique = true)

to make it unique on the field

IamMax420OP•2w ago

Damn alr

ayylmao123xdd•2w ago

instead of that table annotation
