GitLab Runner 在 GitLab 注册表中找不到父 POM

Question

I want a GitLab Runner to build a Java/Maven project. My problem is that Maven can't find the parent POM in the GitLab Registry inside the GitLab Runner, but locally it can.

Running ./mwn install locally builds it. But the runner can't.
Locally I have setup the ~/.m2/settings.xml , do I need to do it in the runner too?

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <artifactId>some-project-lib-common</artifactId>
    <version>0.0.3-SNAPSHOT</version>
    <name>some-project-lib-common</name>
    <description>some-project-lib-common</description>

    <parent>
        <groupId>com.some-project</groupId>
        <artifactId>some-project-maven-parent</artifactId>
        <version>0.0.16</version>
    </parent>


    <repositories>
        <repository>
            <id>gitlab-maven</id>
            <url>https://my.gitlab.instance.com/api/v4/groups/11/-/packages/maven</url>
        </repository>
    </repositories>

    <distributionManagement>
        <repository>
            <id>gitlab-maven</id>
            <url>https://my.gitlab.instance.com/api/v4/projects/21/packages/maven</url>
        </repository>
        <snapshotRepository>
            <id>gitlab-maven</id>
            <url>https://my.gitlab.instance.com/api/v4/projects/21/packages/maven</url>
        </snapshotRepository>
    </distributionManagement>

</project>

The runner produces this error message then:

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM for com.some-project:some-project-lib-common:0.0.3-SNAPSHOT: Could not find artifact com.some-project:some-project-maven-parent:pom:0.0.16 in gitlab-maven (https://my.gitlab.instance.com/api/v4/groups/11/-/packages/maven) and 'parent.relativePath' points at wrong local POM @ line 11, column 13

What did I do wrong?

Thank you in advance!

I did not know that I need to create a settings.xml such that the runner can actually connect/authenticate against the gitlab registry.

See the docs here for more: https://docs.gitlab.com/ee/user/packages/maven_repository/index.html#create-maven-packages-with-gitlab-cicd
