Web Deploy Packages fail on build server

Question

I am using the following MSBuild command form the command prompt:

MSBuild.exe /nologo "Server.Website.csproj" /T:Package 

on a web application (ASP.NET 4 MVC) that relies on a project reference to a Silverlight project. When building, I get the following error:

"C:\Builds\2\Development\Main Branch Nightly\Sources\Components\Server.Website\Server.Website.csproj" (Package target) (1) ->
(CopyAllFilesToSingleFolderForPackage target) ->
C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets(1852,5): error : Copying file Content\ClientBin\Shell.xap to obj\Debug\Package\PackageTmp\Content\ClientBin\Shell.xap failed. Could not find a part of the path 'Content\ClientBin\Shell.xap'.
[C:\Builds\2\Development\Main Branch Nightly\Sources\Components\Server.Website\Server.Website.csproj]

When I omit the /T:Package from the MSBuild call, it seems to work fine. Am I missing something about handing XAPs for build servers on silverlight?

Answer 1

In the Server.Website.csproj project, under

<Project>
   <PropertyGroup>
      <SilverlightApplicationList>

the path to the XAP's project was incorrect. Fixing this issue corrected the problem.
