Java + Lombok + Guava + Validation

I have this Pojo:

@Getter
@EqualsAndHashCode
public class Order {

    public enum OrderType {
        BUY, SELL
    }
    private Id id;
    private Quantity quantity;
    private Money price;
    private OrderType orderType;

    public Order(Id id, Quantity quantity, Money price, OrderType orderType) {

        Preconditions.checkNotNull(id, "id can't be null");
        Preconditions.checkNotNull(quantity, "quantity can't be null");
        Preconditions.checkNotNull(price, "price can't be null");
        Preconditions.checkNotNull(orderType, "orderType can't be null");

        this.id = id;
        this.quantity = quantity;
        this.price = price;
        this.orderType = orderType;
    }

I wish to do three things:

Is this possible?

I also like to use @Builder pattern, can I incorporate Preconditions with this approach?

Mark all fields with @lombok.NonNull and use @RequiredArgsConstructor; that should do it.
