JSF2 + jetty-maven + plugin + jetty9注释问题

Question

我试图设置一个maven项目，以便使用eclipse Luna和jetty-maven-plugin在jetty（非嵌入式）上进行测试，但即使默认情况下应该启用注释，jsf2注释似乎不扫描。 这是我的pom.xml

这是我的managedBean

@ManagedBean
@SessionScoped
public class ManBean {
    final static Logger logger = LoggerFactory.getLogger(ManBean.class);

    @PostConstruct
    public void postConstruct(){
        logger.info(name);  
    }

    public void action(){       
        logger.info("my action");
    }
}

当我触发控制器动作时（通过点击带有ajax行为的jsf按钮）我得到了：

我认为jsf注释没有被扫描但为什么会发生并且有解决方案呢？ 使用mvn jetty：run-war，部署在jetty实例上的生成的war正常工作。
