Grant copy artIfact permission in multi-branch pipeline

Question

I have the following setup:

A Jenkins multi-branch pipeline job configured through Jenkinsfile. After successful checkout and build, the artifact is archived and a downstream job is triggered to deploy the generated artifact.

For the second job to be able to copy the artefact through the [$class: 'CopyArtifact'... step, it needs copy permissions.

So the question is, how do I grant those permissions through the Jenkinsfile of the upstream job?

Answer 1

In declarative pipelines, this is the preferred syntax:

options {
    copyArtifactPermission('my-downstream-project');
}

Available from version 1.41 of Copy Artifact.
