关于maven下载jar报错问题，本地仓库有相关jar包

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-plugin:jar:2.6
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-plugin:jar:2.6
（已经删除响应jar包并且重新maven update 但是依然会弹出报错窗口）
