[FIXED] Maven project use multiple GitLab Package Registry

Issue

I am trying to setup 2 GitLab projects (project a & project b) as the remote maven repository for my other project (project c) using GitLab Maven Package Registry.

Now I have 2 GitLab Maven Package Registry

• project A -> id : 112233
• project B -> id : 445566

So, now I need to set the registry setup in my project C pom.xml file

How I can do that, because we can't have multiple in our pom.xml file

<!--registry setup for project a-->
<repositories>
    <repository>
        <id>gitlab-maven</id>
        <url>https://gitlab.com/api/v4/projects/112233/packages/maven</url>
    </repository>
</repositories>

<distributionManagement>
    <repository>
        <id>gitlab-maven</id>
        <url>https://gitlab.com/api/v4/projects/112233/packages/maven</url>
    </repository>

    <snapshotRepository>
        <id>gitlab-maven</id>
        <url>https://gitlab.com/api/v4/projects/112233/packages/maven</url>
    </snapshotRepository>
</distributionManagement>

<!--registry setup for project b-->
<repositories>
    <repository>
        <id>gitlab-maven</id>
        <url>https://gitlab.com/api/v4/projects/445566/packages/maven</url>
    </repository>
</repositories>

<distributionManagement>
    <repository>
        <id>gitlab-maven</id>
        <url>https://gitlab.com/api/v4/projects/445566/packages/maven</url>
    </repository>

    <snapshotRepository>
        <id>gitlab-maven</id>
        <url>https://gitlab.com/api/v4/projects/445566/packages/maven</url>
    </snapshotRepository>
</distributionManagement>

Solution

If project A and B sit in the same group, then you shall use the group-level Maven endpoint in project C's pom.xml:

<repositories>
  <repository>
    <id>gitlab-maven</id>
    <url>https://gitlab.example.com/api/v4/groups/GROUP_ID/-/packages/maven</url>
  </repository>
</repositories>

Else, I guess you should be able to specify one repository for each:

<repositories>
  <repository>
    <id>gitlab-maven-a</id>
    <url>https://gitlab.com/api/v4/projects/112233/packages/maven</url>
  </repository>
  <repository>
    <id>gitlab-maven-b</id>
    <url>https://gitlab.com/api/v4/projects/445566/packages/maven</url>
  </repository>
</repositories>

/!\ Don't forget to set your Maven authentication credentials in your settings.xml file in either case (unless your project has public visibility). Prefer using the CI_JOB_TOKEN.
