通过代理使用 mvn 和 jib 构建 docker 映像

Question

我正在运行此命令以使用maven 和jib 构建docker 映像
mvn compile jib:dockerBuild -Djib.to.image="$IMAGE_NAME"
这个命令在我的机器上运行得很好，因为它会从互联网上下载一些东西，但是，当我尝试在一个管道（在 AWS 上）中运行它时，情况并非如此，该管道将在需要一个公司网络中运行代理
这个命令我已经试过了：
export MAVEN_OPTS="-DsocksProxyHost=<host> -DsocksProxyPort=<port>"
但它没有用，我不想触摸settings.xml 文件，因为我无权访问它，所以我正在寻找的唯一解决方案是使用上面列出的命令提供代理。
这是命令的整个日志：

有多种方法。首先，查看Oracle doc，了解您可以设置哪些标准 Java 网络属性。

1. 在settings.xml（Maven 设置文件）中设置代理配置。例如，

     <proxies>
       <proxy>
         <id>for-https-proxying</id> <!-- Make sure you use different IDs -->
         <!-- For HTTPS proxying. AFAIK, the Maven doc is wrong about this. -->
         <protocol>https</protocol>
         <host>my.company.proxy.com</host>
         <nonProxyHosts>localhost|srv-abc|*.int</nonProxyHosts>
       </proxy>
       <proxy>
         <id>for-http-proxying</id>
         <protocol>http</protocol>  <!-- for HTTP proxying  -->
         <host>my.company.proxy.com</host>
         <nonProxyHosts>localhost|srv-abc|*.int</nonProxyHosts>
       </proxy>
     </proxies>
   

   查看Maven Settings Reference了解更多详情。

2. 在运行 Jib (JVM) 时设置网络系统属性。例如，一个命令行，

   $ mvn -Dhttp.proxyHost=my.company.proxy.com \
         -Dhttp.proxyPort=... \
         -Dhttp.nonProxyHosts=... \
         -Dhttps.proxyHost=... \
         -Dhttps.proxyPort=... \
         compile jib:build
