Question

我正在尝试使用MSBuild Copy任务将我的构建创建的二进制文件复制到某个文件夹。不幸的是，这个过程无声地失败了。没有发出错误消息，也没有复制文件。

以下是我的.csproj文件的相关部分：

<Target Name="CopyFilesForModule" AfterTargets="AfterBuild">
  <CreateItem Include="bin\**\*.*" Exclude="bin\**\*.pdb;bin\**\*.xml">
    <Output TaskParameter="Include" ItemName="MySourceFiles" />
  </CreateItem>
  <Copy SourceFiles="$(MySourceFiles)" DestinationFolder="Areas\KoobooModule7\bin">
    <Output
          TaskParameter="CopiedFiles"
          ItemName="Changed" />
  </Copy>
  <Message Text="sourcefiles: @(MySourceFiles)" />
  <Message Text="changed:@(Changed)" Importance="high" />
</Target>

正如您所看到的，我已经添加了用于调试目的的消息。我使用以下命令行调用msbuild：

"c:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe" /t:rebuild /verbosity:d
iag KoobooModule7.csproj > buildlog.txt

以下是我的构建日志中的相关摘录：

如您所见，复制的文件为空时，已正确识别要复制的文件。如何找出复制过程失败的原因？

Answer 1

您并未在复制任务中引用MySourceFiles项，而是引用MySourceFiles属性。

<Copy SourceFiles="$(MySourceFiles)" DestinationFolder="Areas\KoobooModule7\bin">

应该是

<Copy SourceFiles="@(MySourceFiles)" DestinationFolder="Areas\KoobooModule7\bin">

为什么MSBuild复制任务不能复制？
