💡 Hint

Common Mistakes

Using a generic or unclear function name.

Forgetting to define the function before calling it.

The reusable step is defined as a function named 'buildApp'. This name is used to call the step later.

Complete the code to call the reusable step 'buildApp' inside the pipeline.

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                [1]()

💡 Hint

Common Mistakes

Calling a function name that was not defined.

Omitting parentheses when calling the function.

The reusable step 'buildApp' is called by using its function name followed by parentheses.

Fix the error in the reusable step definition by completing the missing keyword.

💡 Hint

Common Mistakes

Using 'function' which is not valid Groovy syntax.

Omitting the keyword entirely.

In Jenkins scripted pipeline, reusable steps are defined using the 'def' keyword before the function name.

4fill in blank

hard

Fill both blanks to define and call a reusable step named 'testApp' that prints 'Testing application'.

Jenkins

def [1]() {
    echo '[2]'
}
pipeline {
    agent any
    stages {
        stage('Test') {
            steps {
                testApp()
            }
        }
    }
}

💡 Hint

Common Mistakes

Mismatch between function name and call.

Incorrect or unrelated echo message.

The function name 'testApp' matches the call in the pipeline. The echo message describes the step's action.

5fill in blank

hard

Fill all three blanks to create a reusable step 'deployApp' that takes an environment parameter and prints a deployment message.

Jenkins

def [1](env) {
    echo "Deploying to [2] environment"
}
pipeline {
    agent any
    stages {
        stage('Deploy') {
            steps {
                [3]('production')
            }
        }
    }
}

💡 Hint

Common Mistakes

Using different names for the function in definition and call.

Not using the parameter inside the echo message.

The function is named 'deployApp' and takes 'env' as a parameter. The call uses 'deployApp' with the argument 'production'.
