Не удалось выполнить конвейер Jenkins из-за синтаксической ошибки

Question

У меня есть следующий Jenkinsfile в корне моего проекта на основе Spring Boot, который выполняется в Jenkins и создает проект.

Я совершенно новичок в конвейерном синтаксисе Jenkins.Любая помощь будет принята с благодарностью

Jenkinsfile

pipeline {
    agent any
    tools {
        maven "Maven3"
    }
    stages {
        stage('Build') {
            steps {
                node {
                    def os = System.properties['os.name'].toLowerCase()
                    echo "OS: ${os}"                
                    if (os.contains("linux")) {
                      sh "mvn clean install -DskipTests" 
                    } else {
                      bat "mvn clean install -DskipTests"
                    }
                }
            }
        }
    }
}

Answer 1

1) В Jenkins есть два типа конвейера. Декларативный и Сценарий. Вы смешали два типа синтаксиса и ключевые слова из обоих.

node - ключевое слово для скриптового конвейера. Но в начале скрипта вы объявили Pipeline script. Поэтому, чтобы исправить эту ошибку, вам нужно удалить node.

https://jenkins.io/doc/book/pipeline/

2) Для использования оператора условия вам нужно заключить его в script https://jenkins.io/doc/book/pipeline/syntax/#declarative-steps

3) Вам необходимо утвердить или внести белый список в ваш сценарий. Перейдите в Управление Jenkins -> Утверждение сценария в процессе. И нажмите Одобрить.
