首先在创建前，把这些插件先装上：
Build With Parameters
Parameterized Scheduler
Parameterized Trigger plugin
Persistent Parameter Plugin```
创建pipeline项目：
创建好之后点击配置：进去之后点参数化构建：
上面的"p1"以及“job”后面可以单变量用，然后到最下面配置pipeline:
代码如下：
pipeline {
agent any
stages {
stage('Build') {
steps {
echo 'Building'
echo "${p1}"
build "${job}" #构建项目，用build 'jobname'
build 'freestyle1'
build 'freestyle2'
load '333' #这个经过测试，load这个文件可以读出里面的内容
}
}
stage('Test') {
steps {
echo 'Testing..'
echo "${env.JOB_NAME}" #这个是打印出当前job名字。
}
}
stage('Deploy') {
steps {
echo 'Deploying....'
}
}
}
}
配置完成后可以执行了，点击Build with Parameters，会出现如下界面让你选择：
执行结果为：
```Started by user ljb[Pipeline] nodeRunning on master in /var/jenkins_home/workspace/pipeline-1[Pipeline] {[Pipeline] stage[Pipeline] { (Build)[Pipeline] echoBuilding[Pipeline] echo2[Pipeline] build (Building freestyle1)Scheduling project: freestyle1Starting building: freestyle1 #20[Pipeline] load[Pipeline] { (333)[Pipeline] echo333333[Pipeline] }[Pipeline] // load[Pipeline] fileExists[Pipeline] }[Pipeline] // stage[Pipeline] stage[Pipeline] { (Test)[Pipeline] echoTesting..[Pipeline] echopipeline-1[Pipeline] }[Pipeline] // stage[Pipeline] stage[Pipeline] { (Deploy)[Pipeline] echoDeploying....[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] // node[Pipeline] End of PipelineFinished: SUCCESS```
所以这个比较适合严格要求法办顺序的job，比如:a1,a2,a3,a4,a5依次发版本，这个就比较合适
接下来是对于非pipeline的job添加build with Parameters，下面的是自由风格的job:
选了参数化构建之后，构建按钮就变成了build with Parameters，点击build with Parameters后，就给发送版本加上了版本好了：
初次之外，还何以设置用户认证构建，可以有效保护重要项目！
