Question

我注意到Custom Build Steps在我的Visual Studio 2013中停止工作。例如CMAKE生成的ZERO_CHECK不起作用。我尝试了Troubleshooting Build Customizations的所有内容，但没有任何帮助。

我创建了简单的c ++控制台应用程序，将ReadMe.txt的项目类型从text更改为Custom Build Tool，并将简单命令输入到Command Line。

@echo on
copy %0 test.bat
del c:\1.txt

在项目文件中，它看起来像：

  <ItemGroup>
    <CustomBuild Include="ReadMe.txt">
      <Command Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">@echo on
copy %0 test.bat
del c:\1.txt</Command>
    </CustomBuild>
  </ItemGroup>

在Visual Studio 2012中，一切正常，文件test.bat创建，文件c：\ 1.txt已删除。但是在Visual Studio 2013中它并不起作用。 Visual Studio 2013输出：

您可以在VS2013中看到部分VS2012日志不存在：

1>Using "CustomBuild" task from assembly "Microsoft.Build.CppTasks.Common.v110, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
1>Task "CustomBuild" (TaskId:28)
...
1>Done executing task "CustomBuild". (TaskId:28)

您错过了Outputs元数据。有关信息，请参阅this MSDN page。

<ItemGroup>
<CustomBuild Include="ReadMe.txt">
    <Command Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">
@echo on
copy %0 test.bat
del c:\1.txt
    </Command>
    <Outputs Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">test.bat;%(Outputs)</Outputs>
</CustomBuild>
</ItemGroup>

没有它，我会收到来自CustomBuild任务的警告

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppCommon.targets(170,5): warning MSB8018: No outputs specified for item "ReadMe.txt". Its custom build command will be skipped. [<PATH>\SandboxCpp.vcxproj]
  @echo on
          copy %0 test.bat
          del c:\1.txt (TaskId:15)
Done executing task "CustomBuild". (TaskId:15)

我猜你没有得到Using "CustomBuild" task from assembly的打印输出，因为VS2013日志中的详细程度太低了（那里应该还有更多）。

为什么自定义构建步骤在VS2012中有效但在VS2013中不起作用？
