Answer 1

You need to store your credentials on Jenkins Credentials Store.

Then you will be able to access your credentials with

pipeline {
    agent any 

    environment {
        MY_CREDENTIALS = credentials('my-credentials-on-jenkins')
    }

This will create and populate two environment variables: one for username MY_CREDENTIALS_USR, other for password MY_CREDENTIALS_PSW.

You can then access the environment variables by calling their names:

    stages {

        stage('Calling MY_CREDENTIALS') {
            steps {
                echo "username is $MY_CREDENTIALS_USR
                echo "password is $MY_CREDENTIALS_PSW

You need to store your Git credentials on Jenkins Global Credentials Store. I'm using this method.

stage('Checkout External Project'){
  steps{
  git branch: 'master',
  credentialsId: 'credid',
  url: '[email protected]:muz******/react-app-jenkins.git'
}

}

'githubuserpwd' being the credentials variable name that we given in Jenkins:

pipeline {

    agent any
    environment{
      github = credentials('githubuserpwd')
     }

    stages {

      stage('login to github'){
         steps{
           sh "docker login -u $github_USR -p $github_psw"
           }
       }
    }
}
