How can I tag a project in git from a jenkins declarative pipeline

Question

After a successful build of the projects sources I want to set a tag in git and push it. Here are the relevant parts of my pipeline definition:

pipeline {
    agent {
        docker {
            label 'docker'
            image 'somerepo/maven:3.5.2-jdk-8-alpine'
            args '-v /root/.m2:/root/.m2'
        }
    }

    stages {
        stage('Prepare') {
            environment {
                BITBUCKET = credentials('jenkins-creds')
            }
            steps {
                sh 'git clean -ffdx'
                sh("git config user.name 'jenkins'")
                sh("git config user.email 'x@y.z'")
                // Use .netrc for Git credentials
                sh '''
                    cat >~/.netrc <<.
                    machine bitbucket.server
                    login $BITBUCKET_USR
                    password $BITBUCKET_PSW
                    .
                    '''.stripIndent()
            }
        }
        stage('Validate pom') {
            steps {
                sh 'mvn -B validate'
            }
        }
        stage('Tag the version') {
            steps {
                sh 'printf "Tag the sources %s", "1.2.3"'
                sh 'mvn -B versions:set -DnewVersion=5.1.1'
                sh 'mvn -B scm:tag'
            }
        }
    }
}

This results in following error log:

What is going wrong and/or how can I accomplish my goal tagging the project after each successful build?

Answer 1

I am using the following code to create a git tag and push it to the server. You need to add this stage after the build stage.

stage('Git Push To Origin') {

        steps {
     
            withCredentials([usernamePassword(credentialsId: your_credentials, passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
              

                sh "git tag ${your_tag}"
                sh "git push https://${GIT_USERNAME}:${GIT_PASSWORD}@${repository} ${your_tag}"
            }
        }
    }
