java – 无法在Maven环境中从JAXB生成类

我在Maven环境中使用xjc插件,并尝试从Schema生成类
我可以使用xjc从命令行这样做(创建类),但不能使用maven target generate-sources做同样的事情.
获取以下异常

[ERROR] null[5,30]
org.xml.sax.SAXParseException: A class/interface with the same name "<className>" is already in use. Use a class customization
to resolve this conflict.

任何人都可以帮助我找到这里遗漏的东西.

解决方法

如JAXB网站所述,使用以下Maven插件：

<plugin>
.           <groupId>org.jvnet.jaxb2.maven2</groupId>
            <artifactId>maven-jaxb2-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

http://jaxb.java.net/

看来,你正在使用一个不同的插件(org.codehaus.mojo.jaxb2.XjcMojo在你的堆栈跟踪,Google引导我到http://mojo.codehaus.org/jaxb2-maven-plugin/).
