eclipse创建Maven时一直错误

eclipse创建Maven时一直报
Could not calculate build plan: Plugin
org-apache.maven.plugins:maven-resources-plugin:2.6 or one of its
dependencies could not be resolved: Failed to read artifact descriptor for
org.apache.maven.plugins:maven-resources-plugingjar:2.6
这个错误是缺少什么吗

1.右键->Run as->Maven install
2.如果还不行就强制更新下项目

把C:\Users\用户名.m删除 试试，setting配置成阿里的镜像
