在NexusRepository中找不到项目（使用Maven代理存储库）

我们支持公司代理。我已经安装了Sonatype Nexus存储库管理器

尝试按照此链接设置npm和maven代理存储库。NPM代理设置运行良好，测试项目通过。 但是Maven代理安装程序出现问题。创建了一个使用Maven的测试项目，但遇到了问题。未下载依赖项

我做过的事情
1） 在Nexus中设置HTTP和HTTPS代理（因为我们支持公司代理）

2） 创建了一个Maven代理和Maven托管的存储库，并通过名为Maven public的Maven公共存储库将它们分组

3） 创建了~/.m2/settings.xml，包含以下内容

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">
   <mirrors>
    <mirror>
     <id>NexusRepository</id>
     <url>http://nexusrepohost:8080/repository/maven-public/</url>
     <mirrorOf>*</mirrorOf>
    </mirror>
   </mirrors>
   <proxies>
    <proxy>
      <id>http</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxyserver</host>
      <port>8080</port>
      <username>proxyusername</username>
      <password>proxypassword</password>
      <nonProxyHosts>|127.0.0.1|nexusrepohost</nonProxyHosts>
    </proxy>
    <proxy>
      <id>https</id>
      <active>true</active>
      <protocol>https</protocol>
      <host>proxyserver</host>
      <port>8080</port>
      <username>proxyusername</username>
      <password>proxypassword</password>
      <nonProxyHosts>|127.0.0.1|nexusrepohost</nonProxyHosts>
    </proxy>
  </proxies>
</settings>

注意：

1） 绝对不是代理问题，因为npm tet工作正常，它从npm注册表下载了工件。我可以在Nexus中看到它们

我缺少任何设置？

如果在web浏览器（或curl、netcat等）中转到，会发生什么情况？curl和browser会向我显示这样一条消息“此maven2组存储库无法在此URL处直接浏览”。我会尝试使用带-X参数的mvn来获取调试日志记录。另外，您已经定义了HTTP和HTTPS代理，但似乎只使用HTTP？原始日志来自mvn-X执行。不确定为什么只使用http。Nexus允许我们同时设置https和http代理。maven设置中也设置了相同的设置。所以选择http/https可能是由maven完成的吗？如果nonProxyHosts值看起来不正确，则不应该有一个前导“|”：
