java - MapStruct casts error incompatible types: cannot be converted to

Question

Not sure what happens here but when I do mvn clean install I get following error:

incompatible types: capture#1 of ? cannot be converted to com.sweetchoice.report.entities.WhoDelivers

Mapper class:

@Mapper(uses = {BaseJournalMapper.class})
public interface WhoDeliversMapper {

    WhoDelivers dtoToEntity(WhoDeliversDto whoDeliversDto);

    WhoDeliversDto entityToDto(WhoDelivers whoDelivers);
}

Entity class:

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "who_delivers")
public class WhoDelivers extends BaseJournalEntity{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(columnDefinition = "serial")
    private Long id;

    private String name;
}

BaseJournalEntity/BaseJournalDto:

@Getter
@Setter
@SuperBuilder
@AllArgsConstructor
@NoArgsConstructor
@MappedSuperclass
public class BaseJournalDto {

    private LocalDateTime createdAt;
    private Long createdBy;
    private LocalDateTime updatedAt;
    private Long updatedBy;
}

DTO class:

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class WhoDeliversDto extends BaseJournalDto{

    private Long id;

    private String name;

}

and finally pom.xml:

I'm using Java 11, MapStruct 1.4.1.Final and Lombok 1.18.16

Answer 1

Found an answer on my own.

Just add @SuperBuilder in Entity and DTO classes. More info on this link Documentation
