Papyrus: Impossible to deploy to Maven repository from GitLab pipeline

Summary

Hi, As an experimentation, we try to migrate all the jobs from https://ci.eclipse.org/papyrus/view/DomainServices/ into GitLab Pipeline. Everything seems OK except for Maven deployment. The error is a "Unauthorized (401)" : Caused by: org.apache.maven.plugin.MojoExecutionException: Failed to deploy artifacts: Could not transfer artifact org.eclipse.papyrus.domainservices:parent:pom:0.26.0-20250627.163822-1 from/to repo.eclipse.org (https://repo.eclipse.org/content/repositories/papyrus-snapshots/): status code: 401, reason phrase: Unauthorized (401).

Is there something to configure on the GitLab side ?

Steps to reproduce

The pipeline with error is https://gitlab.eclipse.org/eclipse/papyrus/org.eclipse.papyrus-domainservices/-/jobs/603067#L2522.

What is the current bug behavior?
