How do I pass Jenkins credentials to gradle?

I\'m using the jib Gradle plugin to create a docker image and push it to the Azure Container Registry. I\'ve added username/password credentials to Jenkins so far and need to pa

I had a typo in the username. Passing Jenkins credentials as environment variables works as expected. Here's my code: build.gradle (jib configuration):

jib {
    to {
        image = "myacr.azurecr.io/" + project.name
        tags = ["latest"]
        auth {
            // retrieve from Jenkins
            username "${System.env.ACR_CREDENTIALS_USR}"
            password "${System.env.ACR_CREDENTIALS_PSW}"
        }
    }
    container {
        jvmFlags = ["-Xms512M",  "-Xmx1G"]
        ports = ["5000/tcp", "8080/tcp"]
    }    
}

Jenkinsfile:

pipeline {
...
    environment {
        ACR_CREDENTIALS = credentials('myproject-acr') 
    }

    stages {
        ...
        stage('Push Docker Image to Registry') {
            steps {
                sh "./gradlew jib"
            }
        }
...
