参数化构建这里可以添加选项参数，一些字符串的参数，非常的多。这些参数在流水线执行的时候，它会加入到流水线里面去，最终在流水线运行的时候调用这些参数，选完参数之后再去构建。
写一段groovy脚本，然后返回一个列表，其实也就是数组，之后就可以展示出来了。
所以上面就两种类型，一种是普通类型，一种是带有动作的。最终可以看到参数是需要去写脚本的。
这里面有三种类型，使用前面两种就足够了，都是动态类型的选项参数，都支持去运行一组脚本。
这里面写怎么样复杂的groovy脚本都是可以的，最终你将选项返回出来就可以了。
上面就是普通类型的，还有动态类型的。 还支持是否多选，单选。
动态类型还支持选择参数值，这里可以写关联参数的名称。在这里定义好了之后就可以在代码里面去引用它了。（动态类型根据普通类型的值变化而变化）
如果选ant gradle都没有反应，如果选maven就动态选择了。
if (buildTools .equals("maven")){
return ["mvn clean"]
}else if (buildTools.equals("ant")){
return ["ant"]
}else{
return ["gradle"]
}
实践
下面要完成实践，比如要选分支还是选tag，然后自动的将gitlab上面的标签拿下来。
其实最后的效果就是选择tag，那么就列出该项目下面所有的tag，选择branch就列出该项目下面的所有的branch。
接下来要调用gitlab的api接口了。
现在就是准备调用接口拿到项目的分支信息。
要调用api，那么第一步就需要去获取token。
拿到token之后，然后去gitlab看看接口如何调用。
Branches API | GitLab 找到api的分支，这里还有project_id
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/repository/branches"
[root@jenkins ~]# curl --header "PRIVATE-TOKEN: gL8YqsRqzmjfnZ34N7UR" "http://192.168.11.129/api/v4/projects/2/repository/branches"
[{"name":"master","commit":{"id":"45adcfde1668ea88ec76390b5298122bb175b5d5","short_id":"45adcfde","created_at":"2022-10-21T12:11:38.000+08:00","parent_ids":null,"title":"Update src/org/devops/test.groovy","message":"Update src/org/devops/test.groovy","author_name":"Administrator","author_email":"admin@example.com","authored_date":"2022-10-21T12:11:38.000+08:00","committer_name":"Administrator","committer_email":"admin@example.com","committed_date":"2022-10-21T12:11:38.000+08:00","web_url":"http://gitlab.devops.com/root/devops-library/-/commit/45adcfde1668ea88ec76390b5298122bb175b5d5"},"merged":false,"protected":true,"developers_can_push":false,"developers_can_merge":false,"can_push":true,"default":true,"web_url":"http://gitlab.devops.com/root/devops-library/-/tree/master"}][root@jenkins ~]#
上面就是通过curl或者postman去获取了项目的所有分支信息。后面就是用groovy写一个HTTP请求，然后放到Jenkins作业里面。
header里面要有key和value，所以在postman里面要加上header的信息。
这里使用url去发请求，发请求这里基本上就是设置method，选择请求的类型。之后设置请求头，也就是header里面的信息。最后将请求的信息返回。
返回的是json的map，最后就是去过滤数据就行了。

Finished: SUCCESS最后或者你这样写也行，导入类，写成groovy脚本。
这样就可以将分支拿过去了，tag同理。
Jenkins其实本身就是Java包，里面也可以调用其现成的方法。token的值，怎么保存在Jenkins里面以及如何使用如下：
pipeline {
agent any
stages {
stage('Hello') {
steps {
script{
withCredentials([string(credentialsId: '81605426-8e30-4220-b421-0d2bfdfbe880', variable: 'token')]) {
response = sh returnStdout: true,
script: """
curl --location \
--request GET \
"http://192.168.11.129/api/v4/projects/2/repository/branches" \
--header "PRIVATE-TOKEN: ${token}"
"""
}
response = readJSON text: "${response}"
println(response.name)
}
}
}
}
}
