为什么我的idea配上maven镜像不好用

这个是我本地maven settings.xml

<mirror>
  <id>aliyunmaven</id>
  <mirrorOf>*</mirrorOf>
  <name>阿里云公共仓库</name>
  <url>https://maven.aliyun.com/repository/public</url>
</mirror>

这个是报错

这个是IDEA的日志 2020-01-20 16:35:06,373 [ 24290] INFO - #org.jetbrains.idea.maven - [ERROR] [ERROR] Some problems were encountered while processing the POMs:
