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

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://java.net/projects/maven-jaxb2-plugin/pages/Home
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/).
