How to create dynamic checkbox parameter in Jenkins pipeline? - jenkins

Question

I found out how to create input parameters dynamically from this SO answer
agent any
stages {
stage("Release scope") {
steps {
script {
// This list is going to come from a file, and is going to be big.
// for example purpose, I am creating a file with 3 items in it.
sh "echo \"first\nsecond\nthird\" > ${WORKSPACE}/list"
// Load the list into a variable
env.LIST = readFile (file: "${WORKSPACE}/list")
// Show the select input
env.RELEASE_SCOPE = input message: 'User input required', ok: 'Release!',
parameters: [choice(name: 'CHOOSE_RELEASE', choices: env.LIST, description: 'What are the choices?')]
}
echo "Release scope selected: ${env.RELEASE_SCOPE}"
}
}
}
}
This allows us to choose only one as it's a choice parameter, how to use the same list to create checkbox parameter, so the user can choose more than one as needed? e.g: if the user chooses first and third, then the last echo should print
Release scope selected: first,third or the following is fine too, so I can iterate over and find the true ones Release scope selected: {first: true, second: false, third: true}

Answer 1

I could use extendedChoice as below
agent any
stages {
stage("Release scope") {
steps {
script {
// This list is going to come from a file, and is going to be big.
// for example purpose, I am creating a file with 3 items in it.
sh "echo \"first\nsecond\nthird\" > ${WORKSPACE}/list"
// Load the list into a variable
env.LIST = readFile("${WORKSPACE}/list").replaceAll(~/\n/, ",")
env.RELEASE_SCOPE = input message: 'User input required', ok: 'Release!',
parameters: [extendedChoice(
name: 'ArchitecturesCh',
defaultValue: "${env.BUILD_ARCHS}",
multiSelectDelimiter: ',',
type: 'PT_CHECKBOX',
value: env.LIST
)]
// Show the select input
env.RELEASE_SCOPE = input message: 'User input required', ok: 'Release!',
parameters: [choice(name: 'CHOOSE_RELEASE', choices: env.LIST, description: 'What are the choices?')]
}
echo "Release scope selected: ${env.RELEASE_SCOPE}"
}
}
}
}

Answer 2

There is a booleanParam: https://www.jenkins.io/doc/book/pipeline/syntax/#parameters
parameters {
booleanParam(
name: 'MY_BOOLEAN',
defaultValue: true,
description: 'My boolean'
)
} // parameters
It's oddly named, as all the other param types don't have the "Param" name in them. Eg: string, choice, etc.
