我想通过Jenkins声明性管道设置构建名称和描述，但是找不到正确的方法。我尝试在管道之后使用环境支架，在代理支架中使用节点支架，等等。我总是会收到语法错误。

我的Jenkinsfile的最新版本如下：

pipeline {  
    stages {
        stage("Build") {
            steps {
                echo "Building application..."
                bat "%ANT_HOME%/bin/ant.bat clean compile"
                currentBuild.name = "MY_VERSION_NUMBER"
                currentBuild.description = "MY_PROJECT MY_VERSION_NUMBER"
            }
        }
        stage("Unit Tests") {
            steps {
                echo "Testing (JUnit)..."
            echo "Testing (pitest)..."
                bat "%ANT_HOME%/bin/ant.bat run-unit-tests"
            }
        }
        stage("Functional Test") {
            steps {
                echo "Selenium..."
            }
        }
        stage("Performance Test") {
            steps {
                echo "JMeter.."
            }
        }
        stage("Quality Analysis") {
            steps {
                echo "Running SonarQube..."
                bat "%ANT_HOME%/bin/ant.bat run-sonarqube-analysis"
            }
        }
        stage("Security Assessment") {
            steps {
                echo "ZAP..."
            }
        }
        stage("Approval") {
            steps {
            echo "Approval by a CS03"
            }
        }
        stage("Deploy") {
            steps {
                echo "Deploying..."
            }
        }
    }
    post {      
        always {
            junit '/test/reports/*.xml'
        }
        failure {
            emailext attachLog: true, body: '', compressLog: true, recipientProviders: [[$class: 'CulpritsRecipientProvider'], [$class: 'DevelopersRecipientProvider']], subject: '[JENKINS] MY_PROJECT build failed', to: '...recipients...'
        }
        success {
            emailext attachLog: false, body: '', compressLog: false, recipientProviders: [[$class: 'DevelopersRecipientProvider']], subject: '[JENKINS] MY_PROJECT build succeeded', to: '...recipients...'
        }
    }       
}

错误是：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 11: Expected a step @ line 11, column 5.
                currentBuild.name = "MY_VERSION_NUMBER"
       ^

WorkflowScript: 12: Expected a step @ line 12, column 5.
                currentBuild.description = "MY_PROJECT MY_VERSION_NUMBER"
       ^

理想情况下，我希望能够从build.properties文件或Jenkins构建日志中读取MY_PROJECT和MY_VERSION_NUMBER。关于该要求的任何指导也将不胜感激。

更新

根据我在下面的答案，以下工作有效：

stage("Build") {
    steps {
        echo "Building application..."
        bat "%ANT_HOME%/bin/ant.bat clean compile"

        script {
            def props = readProperties  file: 'build.properties'
            currentBuild.displayName = "v" + props['application.version']
        }
    }

现在，通过读取build.properties文件，可以在管道中自动设置构建版本。
