List all the tags using input (Jenkinsfile)

Question

I'm trying to list all the tags (GitLab) inside an input choise, but I do not know how to do it.

What I want to do is to be able to select the tag and based on that perform the deploy to different environments.

Thank you.

I proposes such a solution working in declarative pipeline with dsl:

1. stage with download repo
2. parse tags based on repo
3. stage with choice parameter

CODE:

pipeline {
    agent  any
    stages {

        stage('PollSCM') {
            steps {
                checkout([$class: 'GitSCM', branches: [[name: 'master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'xxx', url: 'repo']]])
                script {
                    tags = sh(script: "git tag --sort=v:refname | tail -5 ", returnStdout: true).trim()
                }
            }
        }

        stage('CHOICE TAG') {
            steps {
                script {
                    def tag_response = input message: 'blah blah tags',
                            parameters: [choice(choices: "${tags}",  description: 'blah', name: '')]
                    env.tag_response = tag_response
                }

            }
        }

        stage ('echo choose') {
            steps {
                echo "I choose: '${tag_response}'"
            }
        }

    }
}
