jenkins define pipeline variables code example

Example 1: jenkins declarative pipeline variables in stage

pipeline {
    agent any
    environment {
        ENV_NAME = "${env.BRANCH_NAME}"
    }

    // ----------------

    stages {
        stage('Build Container') {
            steps {
                echo 'Building Container..'

                script {
                    if (ENVIRONMENT_NAME == 'development') {
                        ENV_NAME = 'Development'
                    } else if (ENVIRONMENT_NAME == 'release') {
                        ENV_NAME = 'Production'
                    }
                }
                echo 'Building Branch: ' + env.BRANCH_NAME
                echo 'Build Number: ' + env.BUILD_NUMBER
                echo 'Building Environment: ' + ENV_NAME

                echo "Running your service with environemnt ${ENV_NAME} now"
            }
        }
    }
}

Example 2: jenkins declarative pipeline functions

Map modules = [:]
pipeline {
    agent any
    stages {
        stage('test') {
            steps {
                script{
                    modules.first = load "first.groovy"
                    modules.first.test1()
                    modules.first.test2()
                }
            }
        }
    }
}
