Get change request number in Jenkins pipeline

Retrieve the change request number in a Jenkins pipeline based on specific change details by running the snDevOpsGetChangeNumber script.

Before you begin

Role required: Jenkins admin

Procedure

1. In your Jenkins dashboard, open the pipeline for which you want to retrieve the change request number.
2. Navigate to Configure > Pipeline.
3. In the Pipeline script section, update the snDevOpsGetChangeNumber script with the following input parameters:
   • Pipeline Name
     Note:

     For a multi-branch pipeline, the pipeline name must be suffixed with the branch name.
   • Build Number
   • Stage Name
     Note:

     For a nested-stage, the stage name must be prefixed with the parent stage name.
   • Branch Name (only for multi-branch pipeline)

   Note:

   If you do not provide the change request details as input parameters, the change request number associated with the current pipeline and stage will be retrieved.

   Example of a multi-branch pipeline:

   snDevOpsGetChangeNumber (changeDetails: """{ "pipeline_name": "github_multi_branch_pipeline/scratch/release", "build_number": "${env.BUILD_NUMBER}", "stage_name": "Prod/Deploy", "branch_name": "scratch/release" }""");

   Example of a Jenkins pipeline:

   snDevOpsGetChangeNumber (changeDetails: """{ "pipeline_name": "github_pipeline", "build_number": "${env.BUILD_NUMBER}", "stage_name": "Prod/Deploy" }""");

4. Save the script.
5. Navigate to DevOps > Orchestrate > Pipeline Change Requests.
6. Select the change record associated with the pipeline.
7. Approve the change request by selecting  Approved  in the  State  field.
8. In Jenkins, open the pipeline for which you are retrieving the change request number.
9. Select Build Now.
   The change request number associated with the pipeline will be displayed as an output in the pipeline.
