How to get build time stamp from Jenkins build variables?

Question

How can I get build time stamp of the latest build from Jenkins? I want to insert this value in the Email subject in post build actions.

Answer 1

One way this can be done is using shell script in global environment section, here, I am using UNIX timestamp but you can use any shell script syntax compatible time format:

pipeline {

    agent any

    environment {
        def BUILDVERSION = sh(script: "echo `date +%s`", returnStdout: true).trim()
    }

    stages {
        stage("Awesome Stage") {
            steps {
                echo "Current build version :: $BUILDVERSION"
            }
        }
    }
}
