Question

在基于Spring Boot的项目的根目录中有以下Jenkinsfile，该文件在Jenkins中执行并构建了项目。

我对Jenkins管道语法非常陌生。任何帮助将不胜感激

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"
                    }
                }
            }
        }
    }
}

Jenkins错误日志：

Answer 1

1）jenkins中有两种类型的管道。声明式和脚本化。您混合了两种语法和关键字。

node是脚本化管道的关键字。但是在脚本开始时，您声明了管道脚本。因此，要解决此错误，您需要删除node。

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

2）要使用条件语句，您需要将其包装在script中 https://jenkins.io/doc/book/pipeline/syntax/#declarative-steps

3）您需要批准或将脚本列入白名单。转到管理Jenkins->进程内脚本批准。然后按批准。

https://jenkins.io/doc/book/managing/script-approval/

最终结果

pipeline {
    agent any
    tools {
        maven "Maven3"
    }
    stages {
        stage('Build') {
            steps {

                script {
                    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"
                    }
                }

            }
        }
    }
}

由于语法问题，无法执行Jenkins管道
