阿里巴巴Dubbo分布式服务框架已开源

嗯，没错，就是这个问题。非常感谢指正。

大家帮忙看看,我使用2.0.12版本 注册中心zookeeper
但不影响使用，就是老报这个 收集统计信息 错误

这是因为你没有启动SimpleMonitor，或SimpleMonitor没有连上Zookeeper注册中心，参见：
http://code.alibabatech.com/wiki/display/dubbo/Administrator+Guide#AdministratorGuide-SimpleMonitorInstallation

在eclipse中引入 dubbo， 有4个module（dubbo-demo-consumer、dubbo-demo-provider、dubbo-monitor-simple、dubbo-registry-simple）一直存在下面的问题，目前没有找到好的解决办法，临时处理了一下。

maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.

	<id>unpack</id>
	<phase>package</phase>
	<!-- goals>
	   <goal>unpack</goal>
	</goals  -->

谁有好的方法，请分享。谢谢。

已经安装启动了 SimpleMonitor，并且连上了Zookeeper注册中心

还是会出现这个错。

能帮忙看看吗？

忘了说了，使用的zookeeper 是3.4.2

问题已解决，把SimpleMonitor里面替换为zookeeper-3.4.2.jar，增加slf4j-api-1.6.1.jar和slf4j-log4j12-1.6.1.jar ，解决问题

你的问题估计和我一样，用了新版本的 zookeeper

你把SimpleMonitor里面替换为zookeeper-3.4.2.jar，增加slf4j-api-1.6.1.jar和slf4j-log4j12-1.6.1.jar ，解决问题

搞错了

需要增加这个

dubbo.monitor.address=监控IP:7070

每次在我shutdown tomcat 时都会出这个提示，有人遇到没有？
