在MSBuild中的属性组内部是否存在"if"类​​型语句？

Question

我目前必须有两个独立的属性组,它们之间只有两个差异,根据条件设置为具有一个或另一个触发器.这就是我所拥有的:

<!--CAME FROM TEAMBUILD-->
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' != 'Debug|AnyCPU' AND '$(Configuration)|$(Platform)' != 'Release|AnyCPU' AND '$(BuildingInsideVisualStudio)' != 'true' ">
    <PreBuildEvent>
    </PreBuildEvent>
    <PostBuildEvent>
      set MAGE="C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\mage.exe"
      set APPFILE=$(TargetDir)$(TargetName).application
      set MANIFEST=$(TargetPath).manifest
      set CERT=$(ProjectDir)$(TargetName).pfx
      set PROJECTNAME=$(TargetName)
      set CONFIGURATION=$(ConfigurationName)
      set TARGETDIR=$(TargetDir)
      set TEAMBUILD=$True
      Powershell -File "$(ProjectDir)POSTBUILD.ps1"
    </PostBuildEvent>
  </PropertyGroup>

  <!--CAME FROM PUBLISH COMMAND-->
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' != 'Debug|AnyCPU' AND '$(Configuration)|$(Platform)' != 'Release|AnyCPU' AND '$(BuildingInsideVisualStudio)' == 'true' ">
    <PreBuildEvent>
    </PreBuildEvent>
    <PostBuildEvent>
      set MAGE="C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\mage.exe"
      set APPFILE=$(TargetDir)$(TargetName).application
      set MANIFEST=$(TargetPath).manifest
      set CERT=$(ProjectDir)$(TargetName).pfx
      set PROJECTNAME=$(TargetName)
      set CONFIGURATION=$(ConfigurationName)
      set TARGETDIR=$(TargetDir)
      set TEAMBUILD=$False
      Powershell -File "$(ProjectDir)POSTBUILD.ps1"
    </PostBuildEvent>
  </PropertyGroup>

有没有办法根据post build事件中的$(BuildingInsideVisualStudio)值设置teambuild值？就像是

如果($(BuildingInsideVisualStudio)=='true')设置TEAMBUILD = $ True

甚至是什么样的 set TEAMBUILD = $$(BuildingInsideVisualStudio)？

Answer 1

你已经在使用它:Condition.您只需要提取额外的步骤来创建将用作TEAMBUILD值的属性.例如:

<PropertyGroup Condition='$(BuildingInsideVisualStudio)' != 'true' ">
  <TeamBuildValue>FALSE</TeamBuildValue>
</PropertyGroup>

<PropertyGroup Condition='$(BuildingInsideVisualStudio)' == 'true' ">
  <TeamBuildValue>TRUE</TeamBuildValue>
</PropertyGroup>

<PropertyGroup>
  <PreBuildEvent>
  </PreBuildEvent>
  <PostBuildEvent>
    ...
    set TEAMBUILD=$(TeamBuildValue)
    ...
  </PostBuildEvent>
</PropertyGroup>

Answer 2

我可能会尝试选择/其他......而不是 == != 只是一个偏好。因为有一天……你可能会有第三种选择。

“Otherwise”子句（又名，使用一些默认值）更加明确。

<Choose>

    <When Condition=" '$(Computername)'=='MySuperComputer01' ">               
        <PropertyGroup>
            <FavoriteFood>Peanuts</FavoriteFood>
            <FavoriteColor>Red</FavoriteColor>
        </PropertyGroup>
    </When>

    <When Condition=" '$(Computername)'=='MySuperComputer02' ">
        <PropertyGroup>
            <FavoriteFood>Apples</FavoriteFood>
            <FavoriteColor>Yellow</FavoriteColor>
        </PropertyGroup>
    </When>

    <Otherwise>
        <PropertyGroup>
            <FavoriteFood>CrackersDefault</FavoriteFood>
            <FavoriteColor>OrangeDefault</FavoriteColor>
        </PropertyGroup>        
    </Otherwise>
    
</Choose>
