Build fails in TC but not from command line

I have a VB6 build, using msbuild, when i run it from the command line, it works okay, but not when run from TeamCity (4.5.1)

I get..

error MSB4067: The element <asdf> beneath element <ItemGroup> is unrecognised.

I have tried changing element asdf, but get the same issue (with new element name!)

I have other item groups within the msbuild file, they cause no issue.

anyone have any ideas?

heres my msbuild file....


<Target Name="BuildGUI">
<Message Text="VBP File.. $(GUIProjectFile)" />
<CallTarget Targets="UpdateVersion" />
<MSBuild.ExtensionPack.VisualStudio.VB6 TaskAction="Build" Projects="@(ProjectToBuild)"/>

<ItemGroup>
<asdf Include="..\..\Releasables\Executables\GUI\*.Exe" />
</ItemGroup>

<Message Text="Items in group= @(asdf)" />
