Maven jaxb2:xjc 无法生成代码

我已将以下插件添加到 pom.xml 中的 Maven 构建中

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration> 
                <extension>true</extension>                             
                <clearOutputDir>false</clearOutputDir>
                <schemaDirectory>${basedir}/src/main/resources/xsd</schemaDirectory>
                <schemaFiles>myapp.xsd</schemaFiles>                                                        
                <outputDirectory>${basedir}/src/main/java</outputDirectory>         
                <bindingDirectory>src/main/resources/xsd</bindingDirectory>     
                <bindingFiles>myapp-bindings.xjb</bindingFiles>
            </configuration>
        </execution>
    </executions>                       

</plugin>

以下是构建错误。

我很困惑，为什么插件没有引用配置中指定的路径和文件。

版本 2.1 更改了源的指定方式

http://mojo.codehaus.org/jaxb2-maven-plugin/xjc-mojo.html#sources http://mojo.codehaus.org/jaxb2-maven-plugin/xjc-mojo.html#sources

e.g

<configuration>
...
  <sources>
     <source>some/explicit/relative/file.xsd</source>
     <source>/another/absolute/path/to/a/specification.xsd</source>
     <source>a/directory/holding/xsds</source>
 </sources>
</configuration>

我遇到了很多其他问题，所以按照 jshark 的建议坚持使用 1.6 是一个很好的计划
