如何从 Jenkins Pipeline sh 脚本步骤返回 stdout 和 stderr 以及状态

Question

这个问题的答案受到@codeGeass对How toexecute a command in a Jenkins 2.0 Pipeline job and then return the stdout 的回答的评论的启发：

我们可以一起使用它们吗？在变量中捕获 returnStdout 并在另一个变量中捕获 returnStatus ？因为重复 sh 脚本两次并不酷

Answer 1

要返回stdout并stderr结合状态，您可以执行以下操作：

def runScript(command) {
    script {
        sh script: "set +x ; $command 2>&1 && echo \"status:\$?\" || echo \"status:\$?\" ; exit 0", returnStdout: true
    }
}

pipeline {
    agent any

    stages {
        stage('more values from sh') {
            steps {
                script {
                    // inline
                    def stdoutAndStatus = sh script: 'set +x ; ls -a 2>&1 && echo "status:$?" || echo "status:$?" ; exit 0', returnStdout: true
                    echo "stdoutAndStatus: >$stdoutAndStatus<".trim()
                    
                    def stderrAndStatus = sh script: 'set +x ; ls notexisting 2>&1 && echo "status:$?" || echo "status:$?" ; exit 0', returnStdout: true
                    echo "stderrAndStatus: >$stderrAndStatus<".trim()
                    
                    // with function
                    echo "runScript: >${runScript('ls -a')}<".trim()
                    echo "runScript: >${runScript('ls notexisting')}<".trim()
                    
                    // failing the sh step
                    echo "runScript: >${runScript('not_existing_command')}<".trim()
                }
            }
        }
    }
}
