💡 Hint

Common Mistakes

Using a message that indicates an error instead of a welcome message.

Forgetting to use quotes around the message string.

The setSystemMessage method sets the message shown on the Jenkins dashboard. "Welcome to Jenkins!" is a common friendly message.

💡 Hint

Common Mistakes

Passing the number as a string.

Using a word instead of a number.

Using a decimal number.

The setNumExecutors method expects an integer number, so 4 without quotes is correct.

Fill both blanks to configure Jenkins to use the 'admin' user and set the authorization strategy to full control.

Jenkins

jenkins.model.Jenkins.instance.setSecurityRealm(new HudsonPrivateSecurityRealm(false))

jenkins.model.Jenkins.instance.getSecurityRealm().createAccount("[2]", "password")

💡 Hint

Common Mistakes

Using an authorization strategy that requires complex matrix setup.

Not creating the user before setting permissions.

The LoggedInUsersCanDoAnythingAuthorizationStrategy grants full control to logged-in users. The user 'admin' is created with a password.

Fill the blanks to create a new Jenkins job named 'MyJob' of type freestyle and save it.

Jenkins

import hudson.model.FreeStyleProject
import jenkins.model.Jenkins

project = Jenkins.instance.createProject([1], "[2]")
project.save()

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

AFreeStyleProject.class

BMyJob

CFreeStyleProject

DFreestyleProject.class

Attempts:

💡 Hint

Common Mistakes

Using incorrect class names or missing .class suffix.

Not providing the job name as a string.

The createProject method needs the project class and the job name. FreeStyleProject.class is the correct class for freestyle jobs, and "MyJob" is the job name.
