How can I use %(RecursiveDir) and task batching together

How can I use %(RecursiveDir) and task batching together

  Neil,

  Sorry, I missed your post. Your solution works, and it's shorter!

  That didn't work either, but if I split the CreateItem into two, then it works, like so:

  <CreateItem AdditionalMetadata="RealRecDir=%(FilesToCopy.RecursiveDir)" Include="@(FilesToCopy)">
  <Output ItemName="TestEx1" TaskParameter ="Include"/>
  </CreateItem>

  <CreateItem AdditionalMetadata="Hostname=%(Host.HostName" Include="@(TextEx1)">
  <Output ItemName="TestEx2" TaskParameter ="Include"/>
  </CreateItem>

  <Copy SourceFiles="@(TestEx2)" DestinationFiles="@(TestEx2->'$(PublishDir)%(HostName)%(RealRecDir)%(Filename)')"/>

  Thanks for the help.

  Scott,

  I think your case the problem is you have a $(Host.HostName) in there, and your %(RecursiveDir) isn't qualified. Try changing the %(RecursiveDir) to %(HTMLPublishFiles.RecursiveDir) and see if that does the trick. Also, I assume you have a <Target> around this that actually batches on the Host ItemGroup

  Now that I'm thinking about it my use of the RelativeDir may not function properly. Here is a more correct technique I think.

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

  <ItemGroup>

  <Host Include="localhost">

  <Hostname>localhost</Hostname>

  <Domain>$(NamDMZ)</Domain>

  </Host>

  <!-- Development servers-->

  <Host Include="DevServer1">

  <Domain>$(NSRoot)</Domain>

  <Hostname>DevServer1</Hostname>

  <Description>Development server</Description>

  </Host>

  </ItemGroup>

  <ItemGroup>

  <FilesToCopy Include="Source\Ibr\**\*"/>

  </ItemGroup>

  <PropertyGroup>

  <PublishDir>C:\pub\</PublishDir>

  </PropertyGroup>

  <Target Name="PrintFiles">

  <CreateItem AdditionalMetadata="Hostname=%(Host.HostName);RealRecDir=%(FilesToCopy.RecursiveDir)" Include="@(FilesToCopy)">

  <Output ItemName="Test" TaskParameter ="Include"/>

  </CreateItem>

  <Copy SourceFiles="@(Test)" DestinationFiles="@(Test->'$(PublishDir)%(HostName)%(RealRecDir)%(FileName)')"/>

  </Target>

  </Project>

  Ok, I messed around with this some tonight and I'm as confused as you, Scott. I sent mail to our whole MSBuild team to see if they can shed some light. Faisal's up on IM right now scratching his head, too. When I hear back, I'll let you know :)

  Scott,

  Did the CreateProperty method work for you as well It's quite a bit simpler to parse for future maintainers of your build script.

  Scott,

  I have an even better one for you :) Rajeev, master of all things batching, gave this supremely simple version that doesn't require CreateProperty:
  

  <Target Name="Build" Outputs="%(Host.Identity)">

  <Message Text="$(PublishDir)@(Host)\%(HTMLPublishFiles.Identity) "/>

  </Target>

  (Obvously, you can replace the Message task with the Copy task and get the same result)

  What about this approach:

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

  <ItemGroup>

  <Host Include="localhost">

  <Hostname>localhost</Hostname>

  <Domain>$(NamDMZ)</Domain>

  </Host>

  <!-- Development servers-->

  <Host Include="DevServer1">

  <Domain>$(NSRoot)</Domain>

  <Hostname>DevServer1</Hostname>

  <Description>Development server</Description>

  </Host>

  </ItemGroup>

  <ItemGroup>

  <FilesToCopy Include="**\*"/>

  </ItemGroup>

  <PropertyGroup>

  <PublishDir>C:\pub\</PublishDir>

  </PropertyGroup>

  <Target Name="CopyFiles">

  <CreateItem AdditionalMetadata="Hostname=%(Host.HostName)" Include="@(FilesToCopy)">

  <Output ItemName="Test" TaskParameter ="Include"/>

  </CreateItem>

  <Copy SourceFiles="@(Test)" DestinationFiles="@(Test->'$(PublishDir)%(HostName)\%(RelativeDir)%(FileName)')"/>

  </Target>

  </Project>

  You're close, Sayed, but there's an easier way without having to use a funky transform. Just do a CreateProperty (rather than CreateItem) to put the hostname into a property. Then when you do the Copy command it only has to batch on one thing:

  <Target Name="Build" Outputs="%(Host.Identity)">
  <CreateProperty Value="%(Host.HostName)">
  <Output PropertyName="Hostname" TaskParameter="Value"/>
  </CreateProperty>
  
  <Copy SourceFiles="@(HTMLPublishFiles)" DestinationFolder="$(PublishDir)\$(Hostname)\%(HTMLPublishFiles.RecursiveDir)"/>
  </Target>

  Also note that you have to make sure that every Include that's used to create HTMLPublishFiles has a ** in it. In the original example, one of them didn't, which will make the recursion work incorrectly.
