Question

我有一个msbuild脚本，它只包含PropertyGroup：DefaultVariables.msbuild

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <!-- default values if nothing is set in Main.proj -->
  <PropertyGroup>
    <ProjectName Condition="'$(PublishService)'==''">DefaultService</ProjectName>
  </PropertyGroup>
</Project>

PublishService可以根据环境进行更改。我还有一个Variables.msbuild与上面的脚本相同，除了服务名称：

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <!-- default values if nothing is set in Main.proj -->
  <PropertyGroup>
    <ProjectName Condition="'$(PublishService)'==''">ErpService</ProjectName>
  </PropertyGroup>
</Project

我的主构建脚本：BuildMsi.msbuild导入DefaultVariables.msbuild，并有一个目标CreateEnvironmentSpecificInstaller，它调用Msi.msbuild

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="CreateInstaller">

  <PropertyGroup>
    <BaseDir Condition="$(BaseDir)==''">$(MSBuildProjectDirectory)</BaseDir>
  </PropertyGroup>

  <Import Project="DefaultVariables.msbuild" />  

  <!-- Something else -->
  <Target Name="CreateEnvironmentSpecificInstaller" DependsOnTargets="$(SpecificBuildSteps)">
    <MSBuild Projects="$(RedistDir)\Framework\Msi.msbuild" Targets="CreateBatchScripts" StopOnFirstFailure="true" Properties="Configuration=$(Configuration)" RebaseOutputs="true" />
  </Target>

  <Target Name="CreateInstaller" DependsOnTargets="PrintVersion;$(GenericBuildSteps)">
    <MSBuild Condition=" '$(EnvironmentName)' == '**AllEnvironments**' " Projects="$(BaseDir)\$(BtsDeploymentFrameworkDir)\BuildMsi.msbuild" Targets="CreateEnvironmentSpecificInstaller" StopOnFirstFailure="true"
        Properties="Configuration=$(Configuration);" RebaseOutputs="true" />
    <CallTarget Targets="RemoveGeneratedEnvironmentSettings" />
  </Target>
</Project>

在Msi.msbuild脚本中，我添加了一个Import to Variables.msbuild脚本，但是之后的PublishService仍然是DefaultService：

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="CreateInstaller">

  <Import Project="Variables.msbuild" />
  <Target Name="CreateBatchScripts">
    <Message Text="PublishService = $(PublishService)" />
  </Target>
</Project>

如何在运行时覆盖此属性值？

首先，你永远不会给PublishService一个价值。我假设你在DefaultVariables.msbuild中想要做的是

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <!-- default values if nothing is set in Main.proj -->
  <PropertyGroup>
    <PublishService> Condition="'$(PublishService)'==''">DefaultService</PublishService>
  </PropertyGroup>
</Project>

然后，我建议您在Variables.msbuild中重命名该属性并删除条件Condition="'$(PublishService)'==''。由于您已在DefaultVariables.msbuild中为该属性指定了默认值，因此将不会满足该条件，因此不会更改该值。

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <PublishService>ErpService</PublishService>
  </PropertyGroup>
</Project>

MSBuild使用Import覆盖属性值
