java - XJC "Is not part of this compilation"问题

Question

我正在使用 Maven JAXB2 插件从我的 XSD 生成 Java 类。

为此，我使用多次执行，如下所示:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <version>2.2</version>
    <executions>
        <execution>
            <id>xsd1</id>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration>
                <arguments>
                    <argument>-b</argument>
                    <argument>${basedir}/src/main/xjb/xsd1.xjb</argument>
                </arguments>
                <sources>
                    <source>${basedir}/src/main/xsd/xsd1.xsd</source>
                </sources>  
            </configuration>
        </execution>
        <execution>
            <id>xsd2</id>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration>
                <arguments>
                    <argument>-b</argument>
                    <argument>${basedir}/src/main/xjb/xsd2.xjb</argument>
                </arguments>
                <sources>
                    <source>${basedir}/src/main/xsd/xsd2.XSD</source>
                </sources>
                <clearOutputDir>false</clearOutputDir>
            </configuration>
        </execution>
    </executions>
</plugin>

我的XJB:

<jxb:bindings version="2.1" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    schemaLocation="../xsd/xsd1.xsd" node="/xsd:schema">
    <jxb:schemaBindings>
        <jxb:package name="com.example.xsd1" />
    </jxb:schemaBindings>
    <jxb:bindings node="//xsd:element[@name='Name']/xsd:complexType">
        <jxb:class name="NameXsd1" />
    </jxb:bindings>
</jxb:bindings>

<jxb:bindings version="2.1" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    schemaLocation="../xsd/xsd2.xsd" node="/xsd:schema">
    <jxb:schemaBindings>
        <jxb:package name="com.example.xsd2" />
    </jxb:schemaBindings>
    <jxb:bindings node="//xsd:element[@name='Name']/xsd:complexType">
        <jxb:class name="NameXsd2" />
    </jxb:bindings>
</jxb:bindings>

当我执行 mvn clean install 时，出现以下错误:

[ERROR] file:/D:/Dev/myproject/src/main/xjb/xsd1.xjb [3,92] 
com.sun.istack.SAXParseException2; systemId: file:/D:/Dev/myproject/src/main/xjb/xsd1.xjb; lineNumber: 3; columnNumber: 92; "file:/D:/Dev/myproject/src/main/xsd/xsd1.xsd" is not part of this compilation. Is it a mistake for "file:/D:/Dev/myproject/src/main/xsd/xsd2.xsd" ?

有什么想法吗？

谢谢!

jaxb2-maven-plugin 考虑您的两个 XJB 文件。

您必须配置xjbExcludeFilters 或 xjbSources 仅包含一个文件:

<xjbSources>
    <xjbSource>src/main/xjb/xsd1.xjb</xjbSource>
</xjbSources>
