MSBuild error CS2001 : Source file could not be found

Hi everyone,

I'm trying to build an MSBuild project with several stes consisting of one solution , 3 projects and some cmd line scripts and keep getting the same error ... The TeamCity 6.0.3 is running on Windows 2008 R2 (x64). If I build it from inside VS2010 everything is fine. Below is the relevant part :


[15:42:44]: "D:\TeamCity\Wald2SVN\trunk\wald2.csproj_deploy\wald2.csproj_deploy.wdproj.teamcity" (Build target) (1) ->

Inside D:\TeamCity\Wald2SVN\trunk\wald2\wald2.admin.csproj the part looking for the missing files is this :

<ItemGroup>
    <Compile Include="App_GlobalResources\Strings.pl.designer.cs">
      <DependentUpon>Strings.pl.resx</DependentUpon>
      <AutoGen>True</AutoGen>
      <DesignTime>True</DesignTime>
    </Compile>
    <Compile Include="App_GlobalResources\Strings.designer.cs">
      <DependentUpon>Strings.resx</DependentUpon>
      <AutoGen>True</AutoGen>
      <DesignTime>True</DesignTime>
    </Compile>
    <Compile Include="App_GlobalResources\Strings.en-GB.designer.cs">
      <AutoGen>True</AutoGen>
      <DesignTime>True</DesignTime>
      <DependentUpon>Strings.en-GB.resx</DependentUpon>
    </Compile>
    <Compile Include="Controllers\AccountsController.cs" />
...

Any idea is most welcome. Trying to look around in the forum for something similar but nothing.
I will happily provide more details...

Thank you,
Tudor.
