How can I pass a pom.artifactId via pipeline

[Jose Mazzetti]

Hi, I'm building my project as:

```

pipelines:
  default:
    - step:
        script:
          - mvn -B verify
          - export IMAGE_NAME=$DOCKER_HUB_USERNAME/MY_PROJECT:1.0

All good so far, but I want to pass dinamically my pom.artifactId as I used to do it in Jenkins. 

I tried without any luck with: 

"@pom.artifactId@"

Any help please?
