我正在尝试使用jaxb-maven插件使用JAXB将多个XSD转换为不同包中的POJO.我已将其设置为使用多个执行块,第一个执行块执行,然后我收到一条消息:在架构或绑定文件中未检测到任何更改

这是我的pom.xml的摘录:

....

这是我收到的错误消息:

[INFO] --- jaxb2-maven-plugin:1.5:xjc (Application) …

我使用maven-jaxb2-plugin从xsd生成jaxb注释类.我有很多像这样的xsd文件:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="A3">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="loginPartner">
          <xs:complexType>
            <xs:sequence>
              <xs:element type="xs:string" name="login"/>
              <xs:element type="xs:string" name="password"/>
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="A3">
    <xs:complexType>
      <xs:sequence>
        <xs:element type="xs:string" name="errorCode"/>
        <xs:element type="xs:string" name="errorDescription"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

当我运行maven插件时,它给了我一个错误:

[ERROR]解析模式时出错.位置[file:schema1.xsd {10,16}].org.xml.sax.SAXParseException:'A3'已经定义

有没有什么办法解决这一问题？实际上我有很多XSD代表来自/来自服务器的请求/响应消息.我想简化创建,验证,解析消息.也许还有另一种解决方案吗？
