JAXB等于和哈希代码：给出错误

Question

我想让我的pom.xml生成hashCode（）和等于我的JAXB对象上的方法（）。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
<modelVersion>4.0.0</modelVersion> 
<version>0.0.1-SNAPSHOT</version> 
<packaging>jar</packaging> 
<dependencies> 
    <dependency> 
     <groupId>org.jvnet.jaxb2_commons</groupId> 
     <artifactId>jaxb2-commons-lang</artifactId> 
     <version>2.3</version> 
    </dependency> 
</dependencies> 
<build> 
    <plugins> 
     <plugin> 
      <groupId>org.jvnet.jaxb2.maven2</groupId> 
      <artifactId>maven-jaxb2-plugin</artifactId> 
      <version>0.8.3</version> 
      <executions> 
       <execution> 
        <goals> 
         <goal>generate</goal> 
        </goals> 
       </execution> 
      </executions> 
      <configuration> 
       <extension>true</extension> 
       <args> 
        <arg>-XtoString</arg> 
        <arg>-Xequals</arg> 
        <arg>-XhashCode</arg> 
       </args> 
       <plugins> 
        <plugin> 
         <groupId>org.jvnet.jaxb2_commons</groupId> 
         <artifactId>jaxb2-basics</artifactId> 
         <version>0.6.2</version> 
        </plugin> 
       </plugins> 
      </configuration> 
     </plugin> 

    </plugins> 
</build> 

这给出了以下错误虽然...

package org.jvnet.jaxb2_commons.lang does not exist 
package org.jvnet.jaxb2_commons.locator does not exist 
package org.jvnet.jaxb2_commons.locator.util does not exist 
cannot find symbol symbol: class Equals 
cannot find symbol symbol: class HashCode 
cannot find symbol symbol: class ToString 
cannot find symbol symbol : class ObjectLocator 
cannot find symbol symbol : class ToStringStrategy 
cannot find symbol symbol : class HashCodeStrategy 

我GOOGLE了一下，我发现一个有关添加后..

<dependency> 
    <groupId>org.jvnet.jaxb2_commons</groupId> 
    <artifactId>runtime</artifactId> 
    <version>0.4.1</version> 
</dependency> 
<dependency> 
    <groupId>org.jvnet.jaxb2_commons</groupId> 
    <artifactId>testing</artifactId> 
    <version>0.4.1</version> 
    <scope>test</scope> 
</dependency> 

但这没有帮助。

任何人都可以帮助我！

这是我们正在工作的配置集。我相信有一些元素需要“排队”（可以这么说），否则你会得到指示的错误。

一般相关性： -

<dependency> 
     <groupId>org.jvnet.jaxb2_commons</groupId> 
     <artifactId>jaxb2-basics-runtime</artifactId> 
     <version>0.6.4</version> 
    </dependency> 

Maven的JAXB2-插件： -

 <plugin> 
      <groupId>org.jvnet.jaxb2.maven2</groupId> 
      <artifactId>maven-jaxb2-plugin</artifactId> 
      <version>0.8.3</version> 
      <executions> 
       <execution> 
        <goals> 
         <goal>generate</goal> 
        </goals> 
       </execution> 
      </executions> 
      <configuration> 
       <extension>true</extension> 
       <generatePackage>you.package.etc</generatePackage> 
       <args> 
        <arg>-XtoString</arg> 
        <arg>-Xequals</arg> 
        <arg>-XhashCode</arg> 
        <arg>-Xinheritance</arg> 
        <arg>-Xcopyable</arg> 
        <arg>-XenumValue</arg> 
       </args> 
       <plugins> 
        <plugin> 
         <groupId>org.jvnet.jaxb2_commons</groupId> 
         <artifactId>jaxb2-basics</artifactId> 
         <version>0.6.4</version> 
        </plugin> 
       </plugins> 
      </configuration> 
     </plugin>
