为什么“盖镜子的镜子”存储库;错误，尽管在Maven设置中使用HTTPS URL .xml

Question

我的maven版本是3.8.5，以下是maven settings.xml中的镜像config

<mirrors>
<mirror>
      <id>aliyun</id>
      <mirrorOf>*</mirrorOf>
      <name>aliyun</name>
      <url>https://maven.aliyun.com/nexus/content/groups/public/</url>
      <blocked>true</blocked>
    </mirror>
  </mirrors>

。但是它设置了true，然后输出以下错误

为什么如何设置它？

您必须在settings.xml上正确配置中心访问：

 <profiles>
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->
      <repositories>
        <repository>
          <id>central</id>
          <url>https://central</url>
          <releases>
            <enabled>true</enabled>
            <checksumPolicy>fail</checksumPolicy>
          </releases>
          <snapshots>
            <enabled>true</enabled>
            <checksumPolicy>fail</checksumPolicy>
          </snapshots>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>

          <snapshots>
            <enabled>true</enabled>
