MSBuild批处理基于三个自变量 [英] MSBuild Batching on Three Independent Variables

问题描述

我一直在编写基于MSBuild的构建系统，并且到了项目的结尾，我需要通过批处理三个变量来本质上运行一个msbuild文件88次:

I have been writing a build system based on MSBuild, and am to the end of the project where I need to essentially run the one msbuild file 88 times by batching over three variables:

配置=调试； Beta;释放;评估
平台= x86; x64
语言= CN； CS; DE; EN; ES; FR;它; J.P; KO; PL; TW

Configuration = Debug; Beta; Release; Evaluation
Platform = x86; x64
Language = CN; CS; DE; EN; ES; FR; IT; JP; KO; PL; TW

我要构建:
"Debug x86 CN"，"Debug x86 CS"，..."Debug x86 TW"
"Debug x64 CN"，...

I want to build:
"Debug x86 CN", "Debug x86 CS", ... "Debug x86 TW"
"Debug x64 CN", ...

我当然可以定义其中的88个:

I can, of course, define 88 of these:

<ItemGroup>
  <ToBuild Include="Debug_x86_CN">
    <Configuration>Debug</Configuration>
    <Platform>x86</Platform>
    <Language>EN</Language>
  </ToBuild>
<ItemGroup>

然后基于元数据进行批处理.但是，真是太累了！我可以在代码中创建88个排列，因此添加语言就像向ItemGroup添加三个字符一样简单:

And then batch based on metadata. But what a drag! Can I create the 88 permutations in code, so adding a language is as easy as adding three characters to an ItemGroup:

<ItemGroup>
  <AllConfigurations Include="Beta; Release; Evaluation;"/>
  <AllPlatforms Include="x86; x64" />
  <AllLanguages Include="CN; CS; DE; EN; ES; FR; IT; JP; KO; PL; TW" />
</ItemGroup>

Thanks to Anders Ljusberg for posting an answer to this years ago. The solution is to use the CreateItem task to combine the individual ItemGroups into one ItemGroup. The cross product of each item needs to be done one at a time into a new ItemGroup (in this case _Config_X_Language and _Config_X_Language_X_Platform) to prevent empty metadata from leaking in (if you try to reuse _Config_X_Language, you'll get items with empty Platform, n addition to the platforms in $(Platform).

<ItemGroup>
  <Configuration Include="Beta; Release; Evaluation;"/>
  <Platform Include="x86; x64" />
  <Language Include="CN; CS; DE; EN; ES; FR; IT; JP; KO; PL; TW" />
</ItemGroup>

<!-- Create an ItemGroup that is the cross product of Configuration and Language: -->
<CreateItem Include="@(Configuration)" AdditionalMetadata="Language=%(Language.Identity);" >
  <Output ItemName="_Config_X_Language" TaskParameter="Include"/>
</CreateItem>
<!-- Create another ItemGroup that is the cross product of _Configuration_X_Language and Platform: -->
<CreateItem Include="@(_Config_X_Language)" AdditionalMetadata="Platform=%(Platform.Identity);" >
  <Output ItemName="_Config_X_Language_X_Platform" TaskParameter="Include"/>
</CreateItem>

<!-- Task batch over each unique set of metadata on AllBuilds -->
<MSBuild Projects="myproject.msbuild"
          Properties="Configuration=%(_Config_X_Language_X_Platform.Identity);
                      Platform=%(_Config_X_Language_X_Platform.Platform);
                      Language=%(_Config_X_Language_X_Platform.Language);"
          Targets="MyTarget"
          BuildInParallel="true" />
