如何修复'创建maven项目时找不到前缀'archetype'错误的插件

Question

我尝试使用以下命令创建Maven项目：

mvn archetype:generate

不幸的是，它没有用，所以我在网上搜索。感谢stackoverflow，我明白错误与我公司的代理有关，所以我在下面创建了一个settings.xml文件：

$ {}的user.home /。平方米/ settings.xml中

这是settings.xml文件：

<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">

  <proxies>
    <proxy>
      <id>my_id</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>my_host</host>
      <port>my_port</port>
      <nonProxyHosts>localhost|127.0.0.1|*.my_company.com</nonProxyHosts>
    </proxy> 
  </proxies>
</settings>

代理标签是由同事给出的，应该是正确的。 但是，我仍然有错误，这是错误消息：

我想知道主机或端口号是否错误，所以我试图多次更改它以查看会发生什么。 当我将端口号更改为随机端口时，我仍然有相同的错误，但过程显着减慢。 我在这个网站和其他网站上搜索了几个小时的解决方案，但仍然找不到灵魂。 我真的很抱歉，如果我在这个问题上犯了一个错误，但我花了半个小时来制作它，并确保遵循指示。 先感谢您。 :) P.S：对不起，对于英语错误，它不是我的主要语言。

我找到了一个解决方案，我更改了settings.xml服务器标签。 我把它改成了Nexus网址，所以，我下载了我公司的罐子。 如果您的SSL证书存在同样的问题，我需要在JAVA中导入证书。

sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标的有效证书路径
