[FIXED] Does not work credentials in Jenkins pipeline

Issue

I have created credentials (method: username and password) in Jenkins with name wwe_hello. For test, i created pipeline with name test:

pipeline {
    agent {label 'slave1'}
    environment {
        CREDS = credentials("wwe_hello")
    }      
    stages {
        stage('WWE') {

            steps {
                sh 'echo "$CREDS"'
            }
        }
    }
}

In result i have:

Running in Durability level: MAX_SURVIVABILITY
[Pipeline] Start of Pipeline
[Pipeline] node
Running on slave1 in /var/lib/jenkins/workspace/test
[Pipeline] {
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
ERROR: wwe_hello
Finished: FAILURE

Where, i have error. I am doing everything according to working examples and documentation. But i don't understand, why it does not work.

Solution

Look at the pipeline step documentation for withCredentials. You don't need to create the environment variable with env - withCredentials does it for you:

pipeline {
    agent any
    stages {
        stage('only') {
            steps {
                withCredentials([
                    usernamePassword(
                        credentialsId: 'CRED', 
                        usernameVariable: 'USER', 
                        passwordVariable: 'PASS'
                        )]) {
                    sh '''
                        echo "The username is: ${USER}"
                        echo "The password is : ${PASS}"
                    '''
                }
            }
        }
    }
}
