方式一：
需要安装插件：Build Name and Description Setter

pipeline {
    agent any

    stages {
        stage('Hello') {
            steps {
                echo 'Hello World'
                buildDescription "构建人：admin"
            }
        }
    }
}

方式二：
安装插件：build-user-vars-plugin

pipeline {
    agent any
    stages {
        stage('test') {
            steps {
                wrap([$class: 'BuildUser']) {
                    script {
                        BUILD_USER = "${env.BUILD_USER}"
                        currentBuild.description = " 构建人 ： ${BUILD_USER}"
                    }           
                }
                
            }
        }
    }
}

方式三：
安装插件 pipeline-utility-steps(Pipeline Utility Steps)
