Copying artifacts between jobs in Jenkins - Practice Problems & Coding Challenges

Challenge - 5 Problems

💻 Command Output

What is the output of this Jenkins pipeline snippet?

Consider this Jenkins pipeline stage that copies artifacts from a previous job named BuildJob:

stage('Copy Artifacts') {
  steps {
    copyArtifacts(projectName: 'BuildJob', selector: lastSuccessful())
  }
}

What happens when this stage runs?

Jenkins

stage('Copy Artifacts') {
  steps {
    copyArtifacts(projectName: 'BuildJob', selector: lastSuccessful())
  }
}

A Copies artifacts from the last successful build of 'BuildJob' into the current workspace.

B Triggers 'BuildJob' to run and copies its artifacts immediately.

C Copies artifacts from the current job to 'BuildJob'.

D Fails because 'copyArtifacts' requires a build number, not a selector.

💡 Hint

Think about what lastSuccessful() means in Jenkins.

The copyArtifacts step with lastSuccessful() selector copies artifacts from the last successful build of the specified project into the current job's workspace.

❓ Configuration

Which Jenkinsfile snippet correctly copies artifacts from a specific build number?

You want to copy artifacts from build number 42 of the job named TestJob. Which snippet does this correctly?

A copyArtifacts(projectName: 'TestJob', selector: build('42'))

B copyArtifacts(projectName: 'TestJob', buildNumber: 42)

C copyArtifacts(projectName: 'TestJob', selector: specific('42'))

D copyArtifacts(projectName: 'TestJob', selector: specificBuild(42))

💡 Hint

Look for the correct selector method for a specific build number.

The specific('42') selector is the correct way to specify a particular build number as a string in copyArtifacts.

❓ Troubleshoot

advanced

Why does this Jenkins pipeline fail to copy artifacts?

Given this pipeline snippet:

stage('Copy') {
  steps {
    copyArtifacts(projectName: 'NonExistentJob', selector: lastSuccessful())
  }
}

The pipeline fails with an error about missing artifacts. What is the most likely cause?

A The job 'NonExistentJob' does not exist or has no successful builds.

B The <code>copyArtifacts</code> step requires a build number, not a selector.

C The pipeline workspace is not writable.

D The <code>copyArtifacts</code> plugin is not installed.

💡 Hint

Check if the source job exists and has successful builds.

If the source job does not exist or has no successful builds, copyArtifacts cannot find artifacts to copy, causing failure.

🔀 Workflow

advanced

What is the correct order to copy artifacts between jobs in a multi-stage pipeline?

Arrange these steps in the correct order to copy artifacts from a build stage to a deploy stage within the same pipeline:

A 4,2,1,3

B 1,4,2,3

C 2,1,4,3

D 4,1,2,3

💡 Hint

Think about preparing workspace, building, copying, then deploying.

First clean workspace, then build and archive artifacts, then copy artifacts, finally deploy.

✅ Best Practice

expert

Which practice ensures reliable artifact copying between Jenkins jobs?

Choose the best practice to avoid failures when copying artifacts between jobs in Jenkins pipelines.

A Copy artifacts without specifying a build selector to get the latest.

B Always archive artifacts in the source job before copying them.

C Use workspace sharing instead of artifact copying.

D Disable artifact archiving to speed up the pipeline.

💡 Hint

Think about what makes artifacts available for copying.

Artifacts must be archived in the source job to be available for copying. Without archiving, copying fails.
