Complete the code to disable deferred wipeout in the Jenkins workspace cleanup step.

Jenkins

steps {
  cleanWs(disableDeferredWipeout: [1])
}

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

AdisableDeferredWipeout()

BdisableDeferredWipeout

Ctrue

Dfalse

💡 Hint

Common Mistakes

disableDeferredWipeout() or disableDeferredWipeout without ': true' causes a syntax error.

Using false keeps the default deferred wipeout behavior.

The cleanWs step accepts disableDeferredWipeout: true to disable deferred deletion. Use the boolean true after the colon.

Complete the code to delete old builds after 10 days.

Jenkins

properties {
  buildDiscarder(logRotator([1]: 10))
}

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

💡 Hint

Common Mistakes

Using daysToKeepStr instead of daysToKeep causes type errors.

Using numToKeep controls number of builds, not days.

The logRotator step uses daysToKeep to specify how many days to keep builds before deleting.

Fix the error in the code to archive artifacts only if they exist.

Jenkins

post {
  always {
    archiveArtifacts artifacts: '[1]', allowEmptyArchive: true
  }
}

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

A**/*.jar

B**/*.txt

C**/*.xml

D**/*.log

Attempts:

3 left

💡 Hint

Common Mistakes

Using a pattern that does not match existing files causes no artifacts archived.

Not setting allowEmptyArchive to true causes build failure if no files found.

Using '**/*.log' archives all log files and allowEmptyArchive: true prevents errors if none exist.

4fill in blank

hard

Fill both blanks to configure disk usage cleanup with days and number of builds.

Jenkins

properties {
  buildDiscarder(logRotator([1]: 7, [2]: 5))
}

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

AdaysToKeep

BnumToKeep

CartifactNumToKeep

DartifactDaysToKeep

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing artifactDaysToKeep with numToKeep causes unexpected behavior.

Using artifactNumToKeep instead of numToKeep affects artifacts, not builds.

daysToKeep sets how many days to keep builds; numToKeep sets how many builds to keep.

5fill in blank

hard

Fill all three blanks to archive only jar files, keep 3 builds, and keep artifacts for 14 days.

Jenkins

properties {
  buildDiscarder(logRotator([1]: 3, [2]: 14))
}

post {
  success {
    archiveArtifacts artifacts: '[3]'
  }
}

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

C**/*.jar

DdaysToKeep

Attempts:

💡 Hint

Common Mistakes

Confusing daysToKeep with artifactDaysToKeep.

Using wrong artifact pattern causes no files archived.

numToKeep limits builds kept; artifactDaysToKeep limits artifact retention days; '**/*.jar' archives jar files.
