@MAPSTRUCT. No property named "packaging" exists in source parameter(s)

Я пишу MVC Rest-приложение. Использую Spring и Hibernate. Решил делать маппинг в DTO через Mapstruct. Кажется, я все делал по инструкции, но выдается ошибка. В чем проблема, я не могу понять. На форумах и в гугле очень мало информации.

P.S. Я не использую в данном случае Ломбок. Геттеры и Сеттеры прописаны вручную.

Drink:

@Entity
@Table(name = "drink", schema = "public")
public class Drink {

    public Drink() { // Constructor for Hibernate

    }


    // Fields
    //
    private @Id
    @GeneratedValue
    Long id;

    @Column(name = "name")
    private String name;

    @Column(name = "price")
    private float price;

    @Column(name = "about")
    private String about;

    @Column(name = "is_deleted")
    private boolean isDeleted;

    // Relationships
    //
    @ManyToOne
    @JoinColumn(name = "packaging_id")
    private Packaging packaging;

    @ManyToOne
    @JoinColumn(name = "manufacturer_id")
    private Manufacturer manufacturer;

    @ManyToOne
    @JoinColumn(name = "country_id")
    private Countries countries;
}

DrinkDTO:

public class DrinkDTO {

    // Fields
    //
    private String drinkName;

    private float drinkPrice;

    private String drinkAbout;

    private Packaging drinkPackaging;

    private Manufacturer drinkManufacturer;

    private Countries drinkCountries;


    // Getters and Setters
    //
    public String getDrinkName() {
        return drinkName;
    }

    public void setDrinkName(String drinkName) {
        this.drinkName = drinkName;
    }

    public float getDrinkPrice() {
        return drinkPrice;
    }

    public void setDrinkPrice(float drinkPrice) {
        this.drinkPrice = drinkPrice;
    }

    public String getDrinkAbout() {
        return drinkAbout;
    }

    public void setDrinkAbout(String drinkAbout) {
        this.drinkAbout = drinkAbout;
    }

    public Packaging getDrinkPackaging() {
        return drinkPackaging;
    }

    public void setDrinkPackaging(Packaging drinkPackaging) {
        this.drinkPackaging = drinkPackaging;
    }

    public Manufacturer getDrinkManufacturer() {
        return drinkManufacturer;
    }

    public void setDrinkManufacturer(Manufacturer drinkManufacturer) {
        this.drinkManufacturer = drinkManufacturer;
    }

    public Countries getDrinkCountries() {
        return drinkCountries;
    }

    public void setDrinkCountries(Countries drinkCountries) {
        this.drinkCountries = drinkCountries;
    }

    // toSTRING
    @Override
    public String toString() {
        return "DrinkDTO{" +
                "drinkName='" + drinkName + ''' +
                ", drinkPrice=" + drinkPrice +
                ", drinkAbout='" + drinkAbout + ''' +
                ", drinkPackaging=" + drinkPackaging +
                ", drinkManufacturer=" + drinkManufacturer +
                ", drinkCountries=" + drinkCountries +
                '}';
    }
