Answer 1

Here is how you can accomplish that

pipeline {
    agent any
    stages {
        stage('first') {
            steps {
                script {
                    withCredentials([usernamePassword(credentialsId: 'COMPOSER_REPO_MAGENTO', passwordVariable: 'MAGE_REPO_PASS', usernameVariable: 'MAGE_REPO_USER')]) {
                        def user = env.MAGE_REPO_USER
                        def password = env.MAGE_REPO_PASS
                        //Initializing a global variable. Notice there is no def here 
                        composerAuth = """{
                            "http-basic": {
                                "repo.magento.com": {
                                    "username": "${user}",
                                    "password": "${password}"
                                }
                            }
                        }"""
                    }
                }
            }
        }
        stage('second') {
            steps {
                script {
                    println composerAuth
                }
            }
        }
    }
}
