Retain stashes so a failed deployment can restart without 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: Operators need Restart from Stage after a deployment failure, but completed-build stashes are discarded.

Requirements:

• Add preserveStashes to Pipeline options
• Retain stashes for 5 completed builds
• Keep Package producing restart-bundle
• Keep Deploy consuming that bundle without rebuilding
