Maven cxf-xjc-plugin xpath在绑定文件中无法按预期工作

问题描述

好，我们走了。为了简单起见，我这里仅提供了几行简单的示例，但仍然无法正常工作。在Web浏览器中进行XPath测试可以找到预期的元素。

插入pom.xml：

<plugin>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-xjc-plugin</artifactId>

                        <additionalJvmArgs>-verbose</additionalJvmArgs>
                        <sourceRoot>${basedir}/src/main/java</sourceRoot>
                        <xsdOptions>
                            <xsdOption>
                                <extension>true</extension>

                                <bindingFiles>
                                    <bindingFile>${basedir}/src/main/resources/xsds/CC015C_bindings.xjb</bindingFile>
                                </bindingFiles>
                                <packagename>generated.messages</packagename>
                            </xsdOption>
                        </xsdOptions>
                    </configuration>
                    <goals>
                        <goal>xsdtojava</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                    <extensions>
                        <extension>org.apache.cxf.xjcplugins:cxf-xjc-dv:3.3.1</extension>
                    </extensions>
            </configuration>
        </plugin>

CC015C.xsd内容：

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
    targetNamespace="http://example.eu"
    elementFormDefault="unqualified"
    attributeFormDefault="unqualified"
    version="51.40"
    vc:minVersion="1.1">
  <complexType name="CC015CType">
  </complexType>
</schema>

CC015C_bindings.xjb（CCType只是我拥有的某个类，应该通过CC015CType进行扩展）：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    jaxb:version="2.1"
>
  <annotation>
    <appinfo>
        <jaxb:bindings schemaLocation="*">
            <jaxb:bindings node="//complexType[@name='CC015CType']">
                <xjc:superClass name="com.example.demo.model.CCType" />
            </jaxb:bindings>
        </jaxb:bindings>
    </appinfo>
  </annotation>
</schema>

运行此命令时，出现此异常：
