jaxb2-maven-plugin雅加达和Java 11

问题描述

我正在尝试迁移到Java 11和雅加达。我需要像在Java EE中一样从XSD文件创建java类。我已将所有jaxb导入都更改为雅加达。但是我不能让jaxb2用jakarta namspace而不是jaxb创建类。如果我没有向插件部分添加任何依赖项，则将使用javax namspace创建该类，而我并不需要该类，并且无论如何都无法找到imorts并出现错误java：package javax.xml.bind.annotation不存在。生成的类是：

package org.ttt.raw.reporting.core.fussnote;
import javax.xml.bind.annotation.XmlAccesstype; // I need to have jakarta.xml.bind ... here!
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
/**

    Java-Klasse für FussnoteType complex type.

    Das folgende Schemafragment gibt den erwarteten Content an,der in dieser Klasse enthalten ist.

    <complexType name="FussnoteType">
    <complexContent>

    &lt;restriction base="{http://www.w3.org/2001/XMLSchema}anyType"&gt;

      &lt;sequence&gt;

        &lt;element name="FussnoteNummer" type="{http://www.w3.org/2001/XMLSchema}string"/&gt;

        &lt;element name="FussnoteText" type="{http://www.w3.org/2001/XMLSchema}string"/&gt;

      &lt;/sequence&gt;

    &lt;/restriction&gt;

    </complexContent>
    </complexType>

*/
@XmlAccessorType(XmlAccesstype.FIELD)
@XmlType(name = "FussnoteType",propOrder = {
"fussnoteNummer","fussnoteText"
})
public class FussnoteType {

@XmlElement(name = "FussnoteNummer",required = true)
protected String fussnoteNummer;
@XmlElement(name = "FussnoteText",required = true)
protected String fussnoteText;

/**
 * Ruft den Wert der fussnoteNummer-Eigenschaft ab.
 * 
 * @return
 *     possible object is
 *     {@link String }
 *     
 */
public String getFussnoteNummer() {
    return fussnoteNummer;
}

/**
 * Legt den Wert der fussnoteNummer-Eigenschaft fest.
 * 
 * @param value
 *     allowed object is
 *     {@link String }
 *     
 */
public void setFussnoteNummer(String value) {
    this.fussnoteNummer = value;
}

/**
 * Ruft den Wert der fussnoteText-Eigenschaft ab.
 * 
 * @return
 *     possible object is
 *     {@link String }
 *     
 */
public String getFussnoteText() {
    return fussnoteText;
}

/**
 * Legt den Wert der fussnoteText-Eigenschaft fest.
 * 
 * @param value
 *     allowed object is
 *     {@link String }
 *     
 */
public void setFussnoteText(String value) {
    this.fussnoteText = value;
}

}

如果我添加了jakarta.xml.bind，那么根本不会生成FussnoteType类，我得到了这些错误：
