不兼容的jaxb依赖项

这回到我的earlier questions之一。 对于JAXB，我基本上遵循this tutorial。因此，我最终得到了这个简化的模型类：

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import java.math.BigDecimal;

/**
 * @author Andi Hotz, (c) Sahits GmbH, 2018
 * Created on Nov 06, 2018
 */
@XmlRootElement(name = "product")
public class Product {
    @XmlAttribute(name = "id")
    private String productId;
    @XmlElement(name = "description")
    private String description;
    @XmlElement(name = "imageUrl")
    private String imageUrl;
    @XmlElement(name = "price")
    private BigDecimal price;
    public Product(){}
    public Product(String productId, String description, String imageUrl,
                   BigDecimal price) {
        this.productId = productId;
        this.description = description;
        this.imageUrl = imageUrl;
        this.price = price;
    }

    @Override
    public String toString() {
        return "Product{" +
                "\n productId='" + productId + '\'' +
                ",\n description='" + description + '\'' +
                ",\n imageUrl='" + imageUrl + '\'' +
                ",\n price=" + price +
                '}';
    }
}

以及导致异常的相应测试（请参见下一节）：

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import java.io.File;
import java.io.FileNotFoundException;
import java.math.BigDecimal;

/**
 * @author Andi Hotz, (c) Sahits GmbH, 2018
 * Created on Nov 06, 2018
 */
class ProductToXmlTest {
    private Product product;

    @BeforeEach
    public void setUp() {
        long l = 10;
        Long longId = new Long(l);
        User user = new User(longId, "John", "john@springframework.guru");
        product = new Product("PO1", "Spring Guru Mug",
                "https://springframework.guru/wp-content/uploads/2015/04/spring_framework_guru_shirt-rf412049699c14ba5b68bb1c09182bfa2_8nax2_512.jpg",
                new BigDecimal(18.95));
    }

    @AfterEach
    public void tearDown() {
        product = null;
    }

    @Test
    public void testObjectToXml() throws JAXBException, FileNotFoundException {
        JAXBContext jaxbContext = JAXBContext.newInstance(Product.class);
        Marshaller marshaller = jaxbContext.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(product, new File("product.xml"));
        marshaller.marshal(product, System.out);
    }
}

该异常表明我缺少某种依赖性，因为AnnotationReader是com.sun.xml.bind.v2.model.annotation.RuntimeAnnotationReader的基本接口，它是jaxb运行时的一部分，但显然不在类路径上。

我还可以想象javax.xml.bind：jaxb-api与org.glassfish.jaxb：jaxb-runtime不完全兼容。

如何设置依赖关系以使其在本示例中起作用？
