根据一组布尔参数创建MSBuild参数字符串 [英] Create MSBuild arguments string based on a set of boolean parameters

问题描述

作为AzureDevops用户，我希望能够通过打开和关闭运行管道"复选框来手动传递不同的MSBuild常量(通过 DefineConstants ).用户界面.
示例:

As a AzureDevops user I want to be able to manually pass different MSBuild constants (via DefineConstants) by turning checkboxes on and off on the "Run Pipeline" UI.
Example:

我通过为当前管道定义两个布尔参数来实现这一目标:

I achieve that by defining two boolean parameters for the current pipeline:

parameters:
- name: enableDebugErrorMessages
  displayName: 'Enable debug error messages'
  type: boolean
  default: false
- name: enableAnalytics
  displayName: 'Enable analytics'
  type: boolean
  default: true

现在，我想为MSBuild生成一个包含启用常量的字符串.例子:

Now I want to generate a string for MSBuild containing enabled constants. Examples:

/p:DefineConstants="ENABLE_ANALYTICS"
/p:DefineConstants="ENABLE_DEBUG_MESSAGES;ENABLE_ANALYTICS"

所以我可以通过这种方式将它们传递给MSBuild:

so I can pass them for MSBuild this way:

- task: XamariniOS@2
  inputs:
    args: '<HERE>'

我尝试了文档除了推荐答案

更新:我在一个琐碎的管道上破解了( another )，并提出了这个解决方案:

UPDATED: I took (another) crack at it on a trivial pipeline and came up with this:

pool: MyBuildPool

parameters:
- name: ENABLE_ANALYTICS
  displayName: "Analytics"
  type: boolean
  default: false
- name: ENABLE_DEBUG_MESSAGES
  displayName: "Debug Messages"
  type: boolean
  default: true
- name: ENABLE_SOMETHING_ELSE
  displayName: "Something Else"
  type: boolean
  default: false

variables:
- ${{ each p in parameters }}:
  - name: "DEFINECONSTANT_${{p.key}}"
    value: ${{ p.value }}
  
steps:
- pwsh: |
    $constantVars = Get-ChildItem -Path Env:\ | Where-Object Name -like "DEFINECONSTANT_*"
    $constantList = ""
    $constantVars | ForEach-Object {
        $constantList += "$($_.Name.Replace('DEFINECONSTANT_', ''))=$($_.Value);"
    }
    Write-Host "/p:DefineConstants=`"$constantList`""
  displayName: 'Combine parameter values'

当我使用Azure Pipelines展开那个文件时，我得到:

When I have Azure Pipelines expand that file, I get:

parameters:
- name: ENABLE_ANALYTICS
  displayName: "Analytics"
  type: boolean
  default: false
- name: ENABLE_DEBUG_MESSAGES
  displayName: "Debug Messages"
  type: boolean
  default: true
- name: ENABLE_SOMETHING_ELSE
  displayName: "Something Else"
  type: boolean
  default: false
variables:
- name: DEFINECONSTANT_ENABLE_ANALYTICS
  value: False
- name: DEFINECONSTANT_ENABLE_DEBUG_MESSAGES
  value: True
- name: DEFINECONSTANT_ENABLE_SOMETHING_ELSE
  value: False
stages:
- stage: __default
  jobs:
  - job: Job
    pool:
      name: MyPoolName
    steps:
    - task: PowerShell@2
      displayName: 'Combine parameter values'
      inputs:
        targetType: inline
        script: |
          $constantVars = Get-ChildItem -Path Env:\ | Where-Object Name -like "DEFINECONSTANT_*"
          $constantList = ""
          $constantVars | ForEach-Object {
              $constantList += "$($_.Name.Replace('DEFINECONSTANT_', ''))=$($_.Value);"
          }
          Write-Host "/p:DefineConstants=`"$constantList`""
        pwsh: true

离您想要的地方更近吗?您可以使用带有不同常量名称，描述和默认值的复选框.

Is that closer to what you want? You can have checkboxes with different constant names, descriptions, and default values.
