通过代理使用mvn和jib构建docker镜像

Question

我运行这个命令来使用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，因为它将从互联网上下载一些东西，当我尝试在管道(在AWS上)中运行它时，情况并非如此，该管道将在需要代理的公司网络中运行
我已经尝试过这个命令：
export MAVEN_OPTS="-DsocksProxyHost=<host> -DsocksProxyPort=<port>"
，但它不起作用，而且我不想触摸settings.xml文件，因为我无权访问它，所以我唯一想要的解决方案是使用上面列出的命令提供代理
这是命令的全部日志：

有多种方法。首先，查看这个Oracle文档，了解您可以设置的标准Java网络属性是什么。

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设置参考以了解更多详细信息。

2. 在运行Jib(JVM)时设置网络系统属性。例如，命令行

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