💡 Hint

Common Mistakes

Using a branch name other than 'main'.

Omitting quotes around the branch name.

The when directive with branch 'main' ensures the stage runs only on the main branch.

Complete the code to run the stage only when the environment variable 'DEPLOY' is set to 'true'.

Jenkins

stage('Deploy') {
  when {
    environment name: 'DEPLOY', value: [1]
  }
  steps {
    echo 'Deploying...'
  }
}

💡 Hint

Common Mistakes

Using 'false' or other values instead of 'true'.

Not quoting the value string.

The when directive checks if the environment variable DEPLOY equals 'true' to run the stage.

Fix the error in the when condition to run the stage only if the branch is 'feature'.

  when {
    branch [1]
  }

💡 Hint

Common Mistakes

Not quoting the branch name.

Using mismatched or incomplete quotes.

The branch name must be a quoted string like 'feature' in the when directive to avoid syntax errors.

4fill in blank

hard

Fill both blanks to run the stage only when the branch is 'release' and the environment variable 'RUN_TESTS' is 'yes'.

Jenkins

stage('Release') {
  when {
    allOf {
      branch [1]
      environment name: 'RUN_TESTS', value: [2]
    }
  }
  steps {
    echo 'Releasing with tests...'
  }
}

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

A'release'

B'yes'

C'no'

D'develop'

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong branch or environment values.

Not quoting the values.

The allOf condition requires both the branch to be 'release' and the environment variable RUN_TESTS to be 'yes' for the stage to run.

5fill in blank

hard

Fill all three blanks to run the stage only when the branch is 'hotfix', the environment variable 'DEPLOY' is 'true', and the build cause is 'SCMTrigger'.

Jenkins

stage('Hotfix Deploy') {
  when {
    allOf {
      branch [1]
      environment name: 'DEPLOY', value: [2]
      triggeredBy '[3]'
    }
  }
  steps {
    echo 'Deploying hotfix...'
  }
}

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

A'hotfix'

B'true'

CSCMTrigger

D'ManualTrigger'

Using wrong trigger cause name.

The stage runs only if the branch is 'hotfix', the environment variable DEPLOY is 'true', and the build was triggered by SCMTrigger.
