Trunk Doris code build failed with repo.maven.apache.org: Name or service not known

[HackToday]

Hi All,

I used latest docker build ways from https://github.com/apache/incubator-doris/blob/master/docs/zh-CN/installing/compilation.md

$ docker pull apache/incubator-doris:build-env-latest

And I clone the latest trunk code today.

But it failed with following:

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

I did have a proxy setting for the docker. That's it (build thirdparty shell scripts works well, so proxy not a issue)

http_proxy=http://xxxx
https_proxy=http://xxxx

but the log seems DNS issue. I did not find similar issue from the github, It was strange.

Could anyone help that ?

have solved
docker not have such mvn settings, it thought host have such settings.
And besides, it needs proxy settings in mvn pom file to make it work.
