How can i find username/details of people who newly pushed code to github? I am using jenkins pipeline to build and deploy

I have created job in jenkins to trigger a build whenever changes happen in github. But i want to know how to get the details of the user who made the changes to configure email notification.

Could anyone help me with the solution please?

You can use git show command to fetch the author ID and email using below command. Assign this to a variable and use it anywhere in the pipeline.

To Fetch Author ID: git show -s --pretty=%an To Fetch Author email: git show -s --pretty=%ae

Pipeline script can be written as like below.

pipeline {
    agent any
    options {
        timestamps()
    }
    stages {
        stage('Test Stage') {
            steps {
                checkout changelog: true, poll: false, scm: [$class: 'GitSCM', branches: [[name: '*/Sample_branch']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'TestCredentials', url: '']]]
                script {
                     Author_ID=sh(script: "git show -s --pretty=%an", returnStdout: true).trim()
                     Author_Name=sh(script: "git show -s --pretty=%ae", returnStdout: true).trim()
                }
                echo "${Author_ID} and ${Author_Name}"
            }
        }
    }
}
