出现原因：maven下载jar包出现问题

解决方案：

直接删除maven-dependency-plugin的jar包，再执行一次maven update ，错误即刻消失。

 

解决方案二：

stackOverflow上有人给出另一种相似的解决方法：

点击Window -> Preferences -> Maven -> Lifecycle Mappings ，点击Open workspace lifecycle mappings metadata，Then add "pluginExecution" entry like in the code below. If the file is empty, copy the entire content below. You might need to change "versionRange".
