Question

Problem Statement: I am getting error like " stderr: remote: Invalid username or password. " for Jenkins build.

My Jenkinsfile is as follows:

node {

    stage('SCM Checkout') {
        git 'https://github.com/xxxxxxxxxxxx/java-app'
    }
        stage('Compile Package'){
        // Get path of Maven Home
        def MavenHome = tool name: 'MVN_HOME', type: 'maven'
        sh "${MavenHome}/bin/mvn package"
    }
}

I have saved my credentials in Jenkins as below:

My Jenkins looks like below:

Unfortunately, I am getting error/log output as below:

Please assist as I want to understand why I am getting an incorrect username and password even though I can login with the same credentials to Github

To get SCM Checkout working we need to add credentials. I did as below:

git changelog: false, credentialsId: 'githubcredentials', poll: false, url: 'https://github.com/xxxxxxxxxxxx/java-app'
