Loop over a list of environment variables inside the environment directive at start of pipeline

[fakemai...@gmail.com]

I haven't found any examples of how to do this

instead of this:

    pipeline {

        agent { label 'docker' }

        environment {

            ENV1 = 'default'

            ENV2 = 'default'

        }

I want to do this:

    pipeline {

        agent { label 'docker' }

        environment {

            for (env in envs) {

               env.name = env.value

            }

        }

maybe I can generate a map before the `pipeline{}` directive and pass it to `environment{}` somehow? I dont want to do this inside of a stage I want this at the top level environment directive for all stages

the environment is a declarative block, what you are trying to make is to define a bunch of variables with a scriptlet block, this is far away from declarative.

The following code make what you want to do

pipeline {

    agent any

    stages {

        stage('test') {

            steps {

               script {

                   [A:1,B:2].each { k, v ->

                       env."${k}" = "${v}"

                   }

                   echo """

                   A = ${env.A}

                   B = ${env.B}

                   """

               }

            }

        }

    }

}
