Can the parameters in a Jenkins declarative pipeline be dynamic?

I want a the choice option values be populated at runtime by a function. The following code does gen

Answer 1

For anyone needing a declarative pipeline syntax option, I found a good solution in another question, which helped me.

This is my suggestion based on it. You should be able to generate a more dynamic list with the code that creates the ${WORKSPACE}/list file

pipeline {
    agent any
    stages {
        stage("Release scope") {
            steps {
                script {
                    // Prepare a list and write to file
                    sh "echo \"patch\nminor\nmajor\" > ${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: 'RELEASE_SCOPE', choices: env.LIST, description: 'What is the release scope?')]
                }
                echo "Release scope selected: ${env.RELEASE_SCOPE}"
            }
        }
    }
}

I hope this helps
