Archiving artifacts in Jenkins - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to archive the build artifacts in Jenkins.

Jenkins

archiveArtifacts '[1]'

Drag options to blanks, or click blank then click option'

Abuild/output/*.jar

Bbuild/output/*.exe

Csrc/*.java

Ddocs/*.md

Attempts:

💡 Hint

Common Mistakes

Using source code files instead of build output files.

Using wrong file extensions like .exe for Java projects.

The archiveArtifacts step archives files matching the given pattern. Here, build/output/*.jar archives all jar files from the build output.

2fill in blank

medium

Complete the code to archive all files inside the 'dist' folder.

Jenkins

archiveArtifacts '[1]'

Drag options to blanks, or click blank then click option'

Abin/*

Bdist/**/*.js

Csrc/*

Ddist/*

Attempts:

💡 Hint

Common Mistakes

Using patterns that only match some files, like '*.js' when other files exist.

Using source folders instead of distribution folders.

The pattern dist/* archives all files directly inside the 'dist' folder.

3fill in blank

hard

Fix the error in the code to archive all files recursively inside 'output' folder.

Jenkins

archiveArtifacts '[1]'

Drag options to blanks, or click blank then click option'

Aoutput/*.txt

Boutput/*

Coutput/**

Doutput

Attempts:

💡 Hint

Common Mistakes

Using single asterisk which does not include subfolders.

Using folder name without wildcard which does not match files.

The pattern output/** archives all files and folders recursively inside the 'output' folder.

4fill in blank

hard

Fill both blanks to archive all '.log' files and exclude 'debug.log'.

Jenkins

archiveArtifacts artifacts: '[1]', excludes: '[2]'

Drag options to blanks, or click blank then click option'

A**/*.log

Bdebug.log

C**/*.txt

Dbuild.log

Attempts:

3 left

💡 Hint

Common Mistakes

Excluding a folder instead of a file.

Using wrong file extensions in patterns.

The artifacts pattern **/*.log archives all log files recursively. The excludes pattern debug.log skips the debug log file.

5fill in blank

hard

Fill all three blanks to archive all '.jar' files, exclude 'test.jar', and allow empty archives.

Jenkins

archiveArtifacts artifacts: '[1]', excludes: '[2]', allowEmptyArchive: [3]

Drag options to blanks, or click blank then click option'

A**/*.jar

Btest.jar

Ctrue

Dfalse

Attempts:

3 left

💡 Hint

Common Mistakes

Setting allowEmptyArchive to false causing build failure.

Wrong exclude pattern causing important files to be skipped.

The artifacts pattern **/*.jar archives all jar files recursively. The excludes pattern test.jar skips the test jar file. Setting allowEmptyArchive to true prevents build failure if no files match.

Practice

1. What is the main purpose of using archiveArtifacts in a Jenkins pipeline?

easy

A. To delete old build files automatically

B. To save build output files for later use or sharing

C. To trigger another build job

D. To send email notifications after a build

Solution

1. Step 1: Understand the role of archiveArtifacts

   This command is used to save files generated by a build so they can be accessed later.

2. Step 2: Compare with other options

   Deleting files, triggering builds, or sending emails are different Jenkins features, not related to archiving artifacts.

3. Final Answer:

   To save build output files for later use or sharing -> Option B

4. Quick Check:

   Archiving = Saving build files [OK]

Hint: Archiving means saving build files for future use [OK]

Common Mistakes:

• Confusing archiving with deleting files
• Thinking it triggers other jobs
• Assuming it sends notifications

2. Which of the following is the correct syntax to archive all .jar files in a Jenkins pipeline script?

easy

A. archiveArtifacts '*.jar'

B. archiveArtifacts '*.jar;'

C. archiveArtifacts '*.jar' {}

D. archiveArtifacts '*.jar'()

Solution

1. Step 1: Recall the syntax of archiveArtifacts

   The correct syntax uses the command followed by the file pattern in quotes without extra characters.

2. Step 2: Identify incorrect syntax

   Options with semicolon, braces, or parentheses after the pattern are invalid in Jenkins pipeline syntax.

3. Final Answer:

   archiveArtifacts '*.jar' -> Option A

4. Quick Check:

   Correct syntax = archiveArtifacts 'pattern' [OK]

Hint: Use single quotes and no extra symbols after pattern [OK]

Common Mistakes:

• Adding semicolons inside the pattern string
• Using braces or parentheses incorrectly
• Missing quotes around the pattern

3. Given this Jenkins pipeline snippet:

stage('Build') {
  steps {
    sh 'echo Hello > output.txt'
    archiveArtifacts 'output.txt'
  }
}

What will Jenkins do after this stage completes?

medium

A. Send output.txt as an email attachment

B. Delete the file output.txt immediately

C. Fail the build because output.txt is not found

D. Save the file output.txt as a build artifact

Solution

1. Step 1: Understand the shell command

   The command creates a file named output.txt with the text 'Hello'.

2. Step 2: Analyze archiveArtifacts usage

   This command archives the specified file so it is saved with the build for later access.

3. Final Answer:

   Save the file output.txt as a build artifact -> Option D

4. Quick Check:

   archiveArtifacts saves files [OK]

Hint: archiveArtifacts saves files created in the build [OK]

Common Mistakes:

• Assuming the file is deleted after archiving
• Thinking the build fails if file exists
• Confusing archiving with emailing files

4. You wrote this Jenkins pipeline snippet:

archiveArtifacts '*.log'

But no files are archived after the build. What is the most likely reason?

medium

A. No .log files were created in the workspace

B. The syntax of archiveArtifacts is incorrect

C. Jenkins does not support archiving .log files

D. The build failed before reaching the archive step

Solution

1. Step 1: Check the file pattern and workspace

   If no .log files exist in the workspace, nothing will be archived.

2. Step 2: Verify syntax and Jenkins support

   The syntax is correct and Jenkins supports archiving any file type.

3. Step 3: Consider build status

   If the build failed before this step, archiving wouldn't run, but the question implies the step ran.

4. Final Answer:

   No .log files were created in the workspace -> Option A

5. Quick Check:

   Files must exist to be archived [OK]

Hint: Check if files exist before archiving [OK]

Common Mistakes:

• Assuming Jenkins can't archive certain file types
• Blaming syntax without checking files
• Ignoring build step execution order

5. You want to archive all .jar files in the build/libs folder and also keep the build logs named build.log. Which archiveArtifacts usage is correct?

hard

A. archiveArtifacts 'build/libs/*.jar', build.log

B. archiveArtifacts 'build/libs/*.jar build.log'

C. archiveArtifacts artifacts: 'build/libs/*.jar, build.log'

D. archiveArtifacts artifacts: 'build/libs/*.jar', 'build.log'

Solution

1. Step 1: Understand multiple file patterns in archiveArtifacts

   To archive multiple patterns, use the named parameter artifacts with a comma-separated string.

2. Step 2: Analyze each option

   archiveArtifacts 'build/libs/*.jar', build.log passes two positional arguments (invalid), archiveArtifacts 'build/libs/*.jar build.log' lacks comma separator, archiveArtifacts artifacts: 'build/libs/*.jar', 'build.log' has invalid syntax with two strings.

3. Final Answer:

   archiveArtifacts artifacts: 'build/libs/*.jar, build.log' -> Option C

4. Quick Check:

   Use artifacts: 'pattern1, pattern2' for multiple files [OK]

Hint: Use artifacts: 'pattern1, pattern2' to archive multiple files [OK]

Common Mistakes:

• Omitting the artifacts: parameter
• Separating patterns without commas
• Passing multiple strings instead of one
