💡 Hint

Common Mistakes

Using a stage name that does not match the task, like 'Test' or 'Deploy'.

Leaving the stage name blank.

The stage block names the pipeline stage. Here, it should be 'Build' to match the task.

💡 Hint

Common Mistakes

Using reserved words like 'env' as variable names.

Using a variable name unrelated to the task.

In Groovy scripts for Jenkins pipelines, variables are declared with def. The variable name here should be 'version'.

hard

Fix the error in the code to correctly run a shell command in a Jenkins pipeline step.

Jenkins

steps {
    sh '[1]'
}

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

Aecho Hello World

Bwrite('Hello World')

Cconsole.log('Hello World')

Dprint('Hello World')

💡 Hint

Common Mistakes

Using programming language print functions instead of shell commands.

Missing quotes around the shell command.

The sh step runs shell commands. echo Hello World is a valid shell command.

4fill in blank

hard

Fill both blanks to create a Jenkins pipeline script that runs a shell command only if the branch is 'main'.

Jenkins

if (env.BRANCH_NAME [1] '[2]') {
    sh 'echo Deploying to production'
}

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

A==

B!=

Cmain

Ddevelop

💡 Hint

Common Mistakes

Using '!=' instead of '==' for equality check.

Using the wrong branch name like 'develop'.

The condition checks if the branch name equals 'main' using == and the string 'main'.

5fill in blank

hard

Fill all three blanks to create a map in Groovy with keys 'name' and 'status', and a condition to include only if status is 'success'.

Jenkins

def result = [[1]: 'Build', [2]: 'success']
if (result.[3] == 'success') {
    echo 'Build succeeded'
}

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

Aname

Bstatus

💡 Hint

Common Mistakes

Mixing up keys and values.

Using incorrect key names in the condition.

The map keys are 'name' and 'status'. The condition checks if result.status equals 'success'.
