Promote the Exact Artifact

Move one immutable build output through promotion instead of rebuilding.

A advanced Jenkins challenge worth 20 points. Solve it hands-on in a real Jenkins environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: Production received different bits than staging because the release stage rebuilt the application.

Requirements:

• In Build, stash dist/** as app-bundle
• In Promote, clean the workspace and unstash that exact bundle
• Archive dist/** with fingerprint: true
• Do not rebuild during promotion
