GitLab CI Maven依赖关系解析失败

Question

I want to setup a CI pipeline in GitLab for my Java project managed with Maven.

This is my gitlab-ci.yml

image: maven:3-jdk-9

variables:
   MAVEN_CLI_OPTS: "--batch-mode"

stages:
   - build

compile:
   stage: build
   script:
       - mvn $MAVEN_CLI_OPTS compile

I always get the following exception:

I tried many things like changing versions of the plugins, various docker images, including a settings.xml and local repository in the project itself, but nothing works.

Thanks in advance for any help!

UPDATE: Using the latest docker image everything works.

Answer 1

It seems like the CI server has no connection to the internet. Check this using the curl command in your .gitlab-ci.yml file.

But I'm pretty sure you guys at daimler have a local mirror, something like Artifactory .
In that case you have to use a settings.xml file.
