Files in ItemGroup not detected by AfterBuild Target - msbuild

Question

What the question should have been:
Here is the content of my ModuleCompilation.targets file :
<ItemGroup>
<ConfigFilesToMove Include="bin\$(Configuration)\*.config"/>
</ItemGroup>
<Target Name="AfterBuild">
<Message Text="Message for AfterBuild" />
<Move SourceFiles="#(ConfigFilesToMove)" DestinationFolder="bin\$(Configuration)\Configuration\" />
</Target>
The Message is written to the console but the files are not moved, how come ?
Original question (you can ignore):
I have included an Import in my csproj file to import a task from another file :
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Import Project="..\ModuleCompilation.targets" />
Now, here is the content of my ModuleCompilation.targets file :
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="14.0" DefaultTargets="AfterBuild" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<BaseFiles Include="bin\$(Configuration)\Libraries\ModuleBase*"/>
<ConfigFilesToMove Include="bin\$(Configuration)\*.config"/>
<OtherFilesToMove Include="bin\$(Configuration)\*" Exclude="bin\$(Configuration)\$(MSBuildProjectName)*" />
</ItemGroup>
<Target Name="AfterBuild">
<Message Text="AfterBuild" />
<Move SourceFiles="#(ConfigFilesToMove)" DestinationFolder="bin\$(Configuration)\Configuration\" />
<Move SourceFiles="#(OtherFilesToMove)" DestinationFolder="bin\$(Configuration)\Libraries\" />
<Message Text="bin\$(Configuration)\Libraries\ModuleBase*" />
<Delete Files="#(BaseFiles)" />
</Target>
</Project>
When I build or rebuild, I do have the "AfterBuild" message in my console, and the files are all indeed generated, but they haven't moved from the Debug folder to where I want them to be.
If I rebuild my projet, the files are moved, I guess because there already were present, but I want to files to be generated and then to be moved, I don't want to have them to be already present !
I must be missing something really obvious, can you help me please ?
Edit:
Ok so I've made some tests and this works :
<ConfigFilesToMove Include="bin\Debug\App.config"/>
While this doesn't:
<ConfigFilesToMove Include="bin\Debug\*.config"/>
Does anyone knowns why ?
Edit 2:
This is really weird, here is my code :
<Project ToolsVersion="14.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<Files Include="$(OutputPath)*.config"/>
<Pouet Include="bin\Debug\*.dll"/>
</ItemGroup>
<Target Name="AfterBuild">
<Message Text="#(Pouet)" />
<Message Text="pouetss" Condition="Exists(#(Pouet))"/>
<Message Text="nooo" Condition="!Exists(#(Pouet))"/>
<MakeDir Directories="$(OutputPath)Configuration\" />
<Copy SourceFiles="#(Pouet)" DestinationFolder="$(OutputPath)Configuration\" />
</Target>
</Project>
Here is what the log from MSBuild says :
1>Target "AfterBuild: (TargetId:75)" in file "C:\Tests\ModuleTest\Modules\ModuleCompilation.targets" from project "C:\Tests\ModuleTest\Modules\FirstModule\FirstModule.csproj" (target "Build" depends on it):
1>Task "Message" (TaskId:47)
1>Done executing task "Message". (TaskId:47)
1>Task "Message" skipped, due to false condition; (Exists(#(Pouet))) was evaluated as (Exists()).
1>Task "Message" (TaskId:48)
1> Task Parameter:Text=nooo (TaskId:48)
1> nooo (TaskId:48)
1>Done executing task "Message". (TaskId:48)
1>Task "MakeDir" (TaskId:49)
1> Task Parameter:Directories=bin\Debug\Configuration\ (TaskId:49)
1> Creating directory "bin\Debug\Configuration\". (TaskId:49)
1>Done executing task "MakeDir". (TaskId:49)
1>Task "Copy" (TaskId:50)
1> Task Parameter:DestinationFolder=bin\Debug\Configuration\ (TaskId:50)
1>Done executing task "Copy". (TaskId:50)
1>Done building target "AfterBuild" in project "FirstModule.csproj".: (TargetId:75)
So MSBuild ignores every value that contains a wildcard ?

Answer 1

Problem :
ItemGroup created outside of a Target are resolved before any Target is run, so you can't target files that a Target will create
Solution :
I changed my code to :
<Target Name="AfterBuild">
<ItemGroup>
<ConfigFilesToMove Include="bin\$(Configuration)\*.config"/>
</ItemGroup>
<Message Text="Message for AfterBuild" />
<Move SourceFiles="#(ConfigFilesToMove)" DestinationFolder="bin\$(Configuration)\Configuration\" />
</Target>
And now my files are detected because the ItemGroup is resolved after the files are created.
