Question

我想在我的MSBuild文件中声明三个属性，并用另一个属性覆盖一个属性（取决于被调用的目标），但无法弄清楚如何执行此操作。我的构建文件看起来像这样：

<PropertyGroup>
   <DeployPath_TEST>\\test-server-path\websites\mysite</DeployPath_TEST>
   <DeployPath_LIVE>\\live-server-path\websites\mysite</DeployPath_LIVE>
   <DeployPath></DeployPath>
</PropertyGroup>

<Target Name="Deploy-TEST">
   <PropertyGroup>
      <DeployPath>$(DeployPath_TEST)</DeployPath>
   </PropertyGroup>
   <CallTarget Targets="Deploy-Sub"/>
</Target>

<Target Name="Deploy-LIVE">
   <PropertyGroup>
      <DeployPath>$(DeployPath_TEST)</DeployPath>
   </PropertyGroup>
   <CallTarget Targets="Deploy-Sub"/>
</Target>

<Target Name="Deploy-Sub">
   <Message Text="Deploying to $(DeployPath)"/>
   <MSBuild Projects="MySolution.csproj" Targets="Rebuild" />

   <ItemGroup>
     <MyFiles Include="**\*"/>
   </ItemGroup>

   <Copy SourceFiles="@(MyFiles)" 
         DestinationFiles="@(MyFiles->'$(DeploymentPath)\%(RecursiveDir)%(FileName)%(Extension)')"/>

</Target>

目前我正在尝试重新声明属性设置它的值，但这不起作用。

Answer 1

Mehmet关于如何从另一个属性设置属性值是正确的，但MSBuild中存在一个错误/特征，这意味着如果在同一个Target中调用CreateProperty和CallTarget，则新属性将不是全局的可用于其他目标（described here）。

所以这是问题的最终解决方案：

<PropertyGroup>
   <DeployPath_TEST>\\test-server-path\websites\mysite</DeployPath_TEST>
   <DeployPath_LIVE>\\live-server-path\websites\mysite</DeployPath_LIVE>
   <DeployPath></DeployPath>
</PropertyGroup>

<Target Name="SetDeployPath-TEST">
  <CreateProperty Value="$(DeployPath_TEST)">
    <Output TaskParameter="Value" PropertyName="DeployPath"/>
  </CreateProperty>
</Target>

<Target Name="Deploy-TEST">
   <CallTarget Targets="SetDeployPath-TEST"/>
   <CallTarget Targets="Deploy-Sub"/>
</Target>

<Target Name="Deploy-Sub">
  <Message Text="Deploying to $(DeployPath)"/>
  <MSBuild Projects="MySolution.csproj" Targets="Rebuild" />

  <ItemGroup>
    <MyFiles Include="**\*"/>
  </ItemGroup>

  <Copy SourceFiles="@(MyFiles)" 
     DestinationFiles="@(MyFiles->'$(DeploymentPath)\%(RecursiveDir)%(FileName)%(Extension)')"/>

</Target>

Answer 2

您可以使用CreateProperty任务覆盖现有属性的值。

<Target Name="Deploy-LIVE">   
  <CreateProperty Value="$(DeployPath_LIVE)">
    <Output PropertyName="DeployPath" TaskParameter="Value"/>
  </CreateProperty>
  <CallTarget Targets="Deploy-Sub"/>
</Target>

Answer 3

我通常会避免CallTarget任务。更好的是使用目标依赖项。

Answer 4

此外，您可以使用以下方式：

<PropertyGroup>
   <DeployPath_TEST>\\test-server-path\websites\mysite</DeployPath_TEST>
   <DeployPath_LIVE>\\live-server-path\websites\mysite</DeployPath_LIVE>
   <DeployPath></DeployPath>
</PropertyGroup>

<Target Name="SetDeployPath-TEST">
  <CreateProperty Value="$(DeployPath_TEST)">
    <Output TaskParameter="Value" PropertyName="DeployPath"/>
  </CreateProperty>
</Target>

<Target Name="Deploy-Sub" DependsOnTargets="SetDeployPath-TEST">
  <Message Text="Deploying to $(DeployPath)"/>
  <MSBuild Projects="MySolution.csproj" Targets="Rebuild" />

  <ItemGroup>
    <MyFiles Include="**\*"/>
  </ItemGroup>

  <Copy SourceFiles="@(MyFiles)" 
     DestinationFiles="@(MyFiles->'$(DeploymentPath)\%(RecursiveDir)%(FileName)%(Extension)')"/>

</Target>

使用MSBuild覆盖属性
