Jenkinsfile with user input with variable in select

Question

I want to use the new Jenkins file for a new job.

I have a jenkinsfile that I have in my solo repository:

• I get branches from another gitlab repository on git ls-remote in bash. And I store them in variables: branch1, branch2, brach3 ....

• Then I want to use these variables in user input options

  script {                
    env.BRANCHDEPLOY = input message: 'User input required',
    ok: 'Deploy!',
    parameters: [choice(name: 'Branch to deploy', choices: '${branch1}\n${branch2}\n${branch3}', description: 'What branch you wont deploy?')]
  }
  echo "${env.BRANCHDEPLOY}"
  

• Then I will use ${env.BRANCHDEPLOY}for git to deploy the selected branch.

The problem is that I can not get to work with variables in the choice of the user.

I just need to let the user select the branch that he wants to deploy from another gitlab repository.

, , script. .

"${branch1}\n${branch2}\n${branch3}"

:

    stage('Stage-One') {
        steps {
            script {                
                env.BRANCHDEPLOY = input message: 'User input required',
                ok: 'Deploy!',
                parameters: [choice(name: 'Branch to deploy', choices: "${branch1}\n${branch2}\n${branch3}", description: 'What branch you wont deploy?')]
            }
        }
    }
    stage('Stage-Two'){
        steps{
            sh "echo ${BRANCHDEPLOY}"
        }
    }
}
