💡 Hint

Common Mistakes

Using 'sh' or 'bat' blocks which run shell or batch commands, not Groovy code.

Trying to use 'groovy' as a block name which is not valid.

The script block allows running Groovy code inside a Jenkins pipeline.

Complete the code to assign a variable inside a Groovy script block.

Jenkins

pipeline {
  agent any
  stages {
    stage('Set Variable') {
      steps {
        script {
          def message = [1]
          echo message
        }
      }
    }

💡 Hint

Common Mistakes

Not using quotes causes syntax errors.

Using single quotes is valid but here double quotes are preferred.

Strings in Groovy must be quoted. Double quotes allow interpolation if needed.

Fix the error in the Groovy script block to correctly loop over a list.

Jenkins

pipeline {
  agent any
  stages {
    stage('Loop') {
      steps {
        script {
          def items = ['a', 'b', 'c']
          for (item [1] items) {
            echo item
          }
        }
      }
    }
  }
}

💡 Hint

Common Mistakes

Using 'of' or '=' causes syntax errors.

Using 'to' is incorrect for looping over collections.

Groovy uses in to loop over collections in for loops.

Fill both blanks to create a Groovy map with keys and values inside a script block.

Jenkins

pipeline {
  agent any
  stages {
    stage('Map') {
      steps {
        script {
          def data = [[1]: 'apple', [2]: 'banana']
          echo data['fruit1']
        }
      }
    }
  }
}

B'fruit2'

Cfruit1

Dfruit2

💡 Hint

Common Mistakes

Using unquoted keys causes errors or treats keys as variables.

Mixing quoted and unquoted keys inconsistently.

Map keys as strings must be quoted. Here keys are 'fruit1' and 'fruit2'.

hard

Fill all three blanks to filter a list inside a Groovy script block using a closure.

Jenkins

pipeline {
  agent any
  stages {
    stage('Filter') {
      steps {
        script {
          def numbers = [1, 2, 3, 4, 5]
          def evens = numbers.findAll { [1] -> [2] [3] 2 == 0 }
          echo evens.toString()
        }
      }
    }
  }
}

💡 Hint

Common Mistakes

Using different names for parameter and variable causes errors.

Using '==' instead of '%' for modulo causes wrong filtering.

The closure uses n -> n % 2 == 0 to find even numbers.
