Active Choice - 动态参数

Jenkins 官网 插件信息

• 需要额外安装
• 支持自定义 html 元素
• 勾选高级里的 Omit value field ，不然参数的值的结尾会多一个逗号 ,

Formatted HTML

• deploy 为参数化构建显示的名称，也是传给后续步骤的环境变量名
• input 标签里的 name 属性必须为 "value" ，value 属性才是需要的变量值

以 checkbox 的 input 为例：

• ${branch} 的值勾选则为 true 否则为 false
• 多个复选框，为 true,true 这种格式

Groovy 示例脚本

html=
'''
<input type="checkbox" name="value" checked>发布到测试环境
'''

default_html=
'''
<p>该分支不支持直接发布，请在构建完成后提交变更请求单</p>
<a href="http://jira.com/secure/CreateIssue!default.jspa" target="_blank" rel="noopener noreferrer">点我提单</a>
'''

if (branch == "devS") {
  return html
} else {
  return default_html
}

配合 Scriptler 插件

先写两个 groovy Scriptler

return ["Select:selected", "DEV", "TEST", "STAGE", "PROD"]

// Static content examples. These lists can be generated dynamically as an alternative.
List devList   = ["Select:selected", "dev1", "dev2"]
List testList  = ["Select:selected", "test1", "test2", "test3"]
List stageList = ["Select:selected", "stage1"]
List prodList  = ["Select:selected", "prod1", "prod2", "prod3", "prod4"]

List default_item = ["None"]

if (Environment == 'DEV') {
  return devList
} else if (Environment == 'TEST') {
  return testList
} else if (Environment == 'STAGE') {
  return stageList
} else if (Environment == 'PROD') {
  return prodList
} else {
  return default_item
}
