在配置Maven依赖信息的时候，出现如下问题：

com.alibaba.nacos:nacos‐client:pom:1.1.3 failed to transfer from http://nexus.hepengju.cn:8081/nexus/content/groups/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of nexus has elapsed or updates are forced.
