When running this with mvn spring-boot, i get the error:

Basic collection has element type ‘uk.ac.rhul.cs2800.model.Grade’ which is not a known basic type (attribute is not annotated ‘@ElementCollection’, ‘@OneToMany’, or ‘@ManyToMany’)

As far as I can tell, the entity and relationships are annotated correctly so I don’t understand why this is happening

This is my first time working with Spring or persistence, and as you can probably tell, this is university work, I really apologise if it’s a badly asked question or lacking any info that I should add.

package uk.ac.rhul.cs2800.model;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.Id;
import jakarta.persistence.JoinColumn;
import jakarta.persistence.ManyToOne;
import jakarta.persistence.OneToOne;

/**
 * class representing Grades.
 */
@Entity
public class Grade {

  @Id
  @GeneratedValue
  Long id;

  @ManyToOne
  @JoinColumn(name = "student_id")
  Student student;


  @OneToOne
  @JoinColumn(name = "module_id")
  Module module;



  public Module getModule() {
    return module;
  }

  public void setModule(Module module) {
    this.module = module;
  }

  public int getScore() {
    return score;
  }

  public void setScore(int score) {
    this.score = score;
  }



  int score;

  /**
   * constructor for Grade.
   *
   * @param score of grade as int.
   * @param module of grade as Module.
   */
  public Grade(int score, Module module) {
    this.score = score;
    this.module = module;
  }
}
