Build docker image using mvn and jib through a proxy

Question

I'm running this command to build docker image using maven and jib
mvn compile jib:dockerBuild -Djib.to.image="$IMAGE_NAME"
this command works perfectly fine on my machine since it's going to download some stuff from the internet, however, it's not the case when I try to run it within a pipeline (on AWS) that is going to run in a corporate network that requires a proxy
I have already tried this command:
export MAVEN_OPTS="-DsocksProxyHost=<host> -DsocksProxyPort=<port>"
but it didn't work, and I don't want to touch the settings.xml file because I don't have access to it, so the only solution I'm loking for is to provide a proxy with the command listed above.
this is the whole log of the command:

Is this entry in the faq helpful? https://github.com/GoogleContainerTools/jib/blob/master/docs/faq.md#how-do-i-configure-a-proxy — loosebazooka, Feb 27 '21 at 14:08

There are multiple ways. First, check out this Oracle doc to understand what are the standard Java networking properties you can set.

Set proxy configuration in settings.xml (the Maven settings file). For example,

  <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>

Check out the Maven Settings Reference for more details.

Set the networking system properties when running Jib (JVM). For example, one the command-line,

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