Question

我正在制作一个maven项目，该项目将利用Jaxb2-maven-plugin从xsd文件生成java文件。我的项目结构如下：

project.basedir
--src/main/resources/schemas
----common
----request
----response

以下是pom.xml的插件配置

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <version>1.6</version>

    <executions>
        <execution>
            <id>xjc-PDF</id>
            <phase>generate-sources</phase>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration>
                <extension>true</extension>
                <clearOutputDir>false</clearOutputDir>
                <outputDirectory>${project.build.directory}/generated-sources/jaxb</outputDirectory>
                <explicitAnnotation>true</explicitAnnotation>
                <!-- <schemaDirectory>${project.basedir}/src/main/resources/schemas</schemaDirectory> -->
                <sources>
                    <source>${project.basedir}/src/main/resources/schemas/common</source>
                    <source>${project.basedir}/src/main/resources/schemas/response</source>
                    <source>${project.basedir}/src/main/resources/schemas/request</source>
                </sources>
                <bindingDirectory>${project.basedir}/src/main/resources/schemas</bindingDirectory>
                <!-- <bindingDirectory>${project.basedir}/src/main/resources/bindings</bindingDirectory> -->
                <bindingFiles>jaxb-bth.xjb</bindingFiles>
            </configuration>
        </execution>
    </executions>
</plugin>

如果我这样编译，那么我得到以下错误（即使源目录包含有效的模式文件）：

但是，如果我评论源代码并取消注释并修改如下所示，那么我可以在常见的模式下生成java类。

<schemaDirectory>${project.basedir}/src/main/resources/schemas/common</schemaDirectory>

有谁能告诉我为什么这样做？如果我必须解析一个根文件夹（有多个子文件夹）下的所有模式文件，该怎么办？

该插件的1.6版不支持“ sources”标签。您可以在2.4版或更高版本上使用“ sources标签。

如果您有多个包含xsds的目录，请在配置中使用多个执行，每个schemaDirectory指向您的目录之一。
