Why Copying artifacts between jobs in Jenkins? - Purpose & Use Cases

The Big Idea

Discover how a simple step can save hours of manual work and prevent costly mistakes in your builds!

The Scenario

Imagine you have two separate Jenkins jobs: one builds your software, and the other runs tests. You need to move the build files from the first job to the second manually.

The Problem

Manually copying files between jobs is slow and risky. You might forget files, copy wrong versions, or waste time searching for the right artifacts. This causes delays and errors in your pipeline.

The Solution

Using artifact copying between jobs automates this transfer. Jenkins securely and reliably passes the exact files needed from one job to another without manual steps.

Before vs After

✗ Before

scp build/output.zip user@server:/test-job/input/
ssh user@server 'cd /test-job && ./run-tests.sh'

✓ After

copyArtifacts(projectName: 'BuildJob', filter: 'output.zip')
sh './run-tests.sh'

What It Enables

This lets your pipeline flow smoothly, saving time and avoiding mistakes by automatically sharing build results between jobs.

Real Life Example

When building a mobile app, the build job creates an APK file. The test job then automatically gets this APK to run tests, ensuring only the latest version is tested.

Key Takeaways

Manual file copying is slow and error-prone.

Copying artifacts automates file sharing between Jenkins jobs.

This improves pipeline speed and reliability.
