如何使用Jenkins管道属性步骤？

Question

所以我用这个脚本创建了一个新的管道（直接粘贴到Jenkins，而不是在SCM中）：

properties [[$class: 'ParametersDefinitionProperty',
   parameterDefinitions: [[$class: 'StringParameterDefinition',
       defaultValue: '', description: '', name: 'PARAM1']]
]]

我运行了它，什么也没有发生，工作没有收到一个新的参数，即使它收到了，我也不明白为什么我可能需要这个。谁能解释一下吗？

Update1:我尝试将一个带有属性步骤的虚拟管道放入我的git repo，然后配置一个多分支作业。

println 1
properties [[$class: 'ParametersDefinitionProperty', parameterDefinitions: [[$class: 'StringParameterDefinition', defaultValue: 'str1', description: '', name: 'PARAM1']]], [$class: 'RebuildSettings', autoRebuild: false, rebuildDisabled: false]]
println 2

Answer 1

将属性与显式方法语法一起使用将起作用，即:
属性([...])而不是属性[...]

或者，如果您指定了参数名称，它也可以在没有参数名称的情况下工作，例如：

properties properties: [ ... ]

例如，定义三个属性非常简单：

properties([
  parameters([
    string(name: 'submodule', defaultValue: ''),
    string(name: 'submodule_branch', defaultValue: ''),
    string(name: 'commit_sha', defaultValue: ''),
  ])
])

/* Accessible then with : params.submodule, params.submodule_branch...  */
