💡 Hint

Common Mistakes

Using a list instead of a newline-separated string.

Using commas inside the string instead of newlines.

The choice parameter expects a string with newline-separated options.

💡 Hint

Common Mistakes

Not quoting the version string.

Using single quotes which may cause syntax issues.

The defaultValue must be a string, so it needs to be quoted with double quotes.

3fill in blank

hard

Fix the error in the code to dynamically generate choices from a Groovy list.

Jenkins

def envs = ['dev', 'qa', 'prod']
properties([parameters([choice(name: 'ENV', choices: [1], description: 'Choose environment')])])

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

Aenvs

Benvs.join('\n')

Cenvs.toString()

Denvs.join(',')

💡 Hint

Common Mistakes

Joining with commas instead of newlines.

Passing the list directly without conversion.

The choices parameter requires a newline-separated string, so joining the list with '\n' is correct.

4fill in blank

hard

Fill both blanks to create a dynamic boolean parameter with a default value.

Jenkins

properties([parameters([booleanParam(name: [1], defaultValue: [2], description: 'Enable feature')])])

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

A"ENABLE_FEATURE"

Btrue

Cfalse

DENABLE_FEATURE

💡 Hint

Common Mistakes

Not quoting the parameter name.

Using string 'true' instead of boolean true.

The name must be a string, so it needs quotes. The defaultValue is a boolean true.

5fill in blank

hard

Fill all three blanks to define a dynamic choice parameter with options generated from a list and a description.

Jenkins

def branches = ['main', 'develop', 'feature']
properties([parameters([choice(name: [1], choices: [2], description: [3])])])

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

A"BRANCH"

Bbranches.join('\n')

C"Select the git branch to build"

Dbranches.toString()

💡 Hint

Common Mistakes

Using toString() for choices instead of joining with newlines.

Not quoting name or description.

The name and description must be strings, so they need quotes. The choices must be a newline-separated string from the list.
