Jenkins管道中的shell脚本是否异步运行？

Question

I have a pipeline for building my android application. In some stages, I have shell scripts. when I run the stages one by one(by commenting others) everything works fine, but when I run them all together I see strange behavior.

It seems that the shell scripts are running in parallel !!

here is my jenkinsfile :

pipeline{
    agent any

    stages{
        stage("Clean"){
          agent{
            node{
              label 'master'
              customWorkspace getMainDirectory()
            }
          }
          steps{
              sh """#!/bin/bash
                rm -rf Corona
                rm -rf native-corona-android
                cd ..
                cp -a TemplateWorkspace/. ${getCoronaBranch()}-${getNativeBrach()}
                """
          }
        }
        stage("pull native repo"){
            agent{
              node{
                label 'master'
                customWorkspace getNativeProjectPath()
              }
            }
            steps{
                echo "pulling native"
                git(
                   url: nativeRepositoryAddress,
                   credentialsId: credentialsId,
                   branch: getNativeBrach()
                )
                echo "pulling done"
            }
        }
        stage("pull corona repo"){
            agent{
              node{
                label 'master'
                customWorkspace getCoronaProjectPath()
              }
            }
            steps{
                echo "pulling corona"
                git(
                   url: coronaRepositoryAddress,
                   credentialsId: credentialsId,
                   branch: getCoronaBranch()
                )
                echo "pulling done"
            }
        }
        stage("build"){
            environment {
                docDir = getMainDirectory()
                ANDROID_HOME = getAndroidSDKLocation()
            }
            agent{
              node{
                label 'master'
                customWorkspace getNativeProjectPath()
              }
            }
            steps{
                sh """#!/bin/bash
                ./gradlew clean
                ./gradlew changeFiles --stacktrace --no-daemon
                ./gradlew assembleDebug --stacktrace --no-daemon
                """
            }
        }
        stage("move build files"){
          agent{
            node{
              label 'master'
              customWorkspace getGradleBuildLocation()
            }
          }
          steps{
              sh """#!/bin/bash
                yes | cp -rf * ../../../../JenkinsBuilds/${getOutputFolder()}/
                """
          }
        }
    }

}

I just want to run steps synchronous(and of course shell scripts), What is my problem?

Here is what I see:

In "Clean" step the folders get deleted and a fresh copy of Template folders get copied to work directory. Steps "pull native repo" and "pull corona repo" do the jobs they should do. but in step "build" I can see that a part of "native-corona-android" files is gone and "gradlew" script is deleted. I have also seen situations where the whole "native-corona-android" folder gets deleted. Then I thought that the script in "Clean" step is called again.

Thanks

Unless you are using parallel directive all steps should be running synchronously.

What behavior do you observe? Which steps are running parallel?
