在pipeline项目中，可以直接在jenkins的web UI上编写pipeline脚本，还有一种方法是使用Jenkinsfile，它放在源码管理库中，比如github、SVN等。为了使pipeline项目管理更加方便，推荐使用这种方式。本文将介绍pipeline项目如何使用Jenkinsfile。
1. 编写jenkinsfile
在持续集成：Jenkins Pipeline语法介绍 中介绍了pipeline支持的两种语法：Declarative 和 Scripted Pipeline。编写pipeline脚本保存为jenkinsfile文本文件，示例脚本如下：
1

| pipeline {
agent any
stages {
stage('begin'){
steps {
echo 'begin'
sleep 2
}
}
stage('running'){
steps {
echo 'running'
script {
RUNNING_STATU = sh (
script: "echo 'running'",
returnStatus: true
) == 0
if ("${RUNNING_STATU}" == "false") {
catchError(stageResult: 'FAILURE') {
echo "执行失败"
}
sh "EXIT 1"
}
}
sleep 2
}
}
stage('finish'){
steps {
echo 'finish'
sleep 2
}
}
}
post {
success {
echo 'success!'
sleep 2
}
failure {
echo 'failed...'
sleep 2
}
always {
echo 'goodbye'
}
}
}
|
保存脚本为文本文件：declareative_helloworld，上传到github或者SVN服务器中。
2. pipeline项目配置
创建一个pipeline项目（可选择Pipeline或者多分支流水线），pipeline脚本定义选择Pipeline script from SCM，
Git库配置方法：
SVN库配置方法：
3. 构建
配置完成后保存，构建时会检出jenkinsfile后执行jenkinsfile中的流水线步骤。比如SVN库的构建日志如下：
