Error building for windows store

Hi,

When trying to build for windows store, I create the visual studio project in Unity, follow the instructions here, and when I try to build using F5, I get the following error:

Code (CSharp):

1. Error    1    The command "echo UnityInstallationDir 'C:\Program Files (x86)\Unity\Editor'
2. echo UnityProjectDir 'C:\Users\Tomer\Documents\Unity Projects\bball_unity'
3. echo Copying assemblies...
4. copy /Y "C:\Users\Tomer\Documents\Unity Projects\bball_unity\Export\win8\Tabletop Basketball\Unprocessed\*" "C:\Users\Tomer\Documents\Unity Projects\bball_unity\Export\win8\Tabletop Basketball\"
5. echo Running AssemblyConverter...
6. "C:\Program Files (x86)\Unity\Editor\Data\PlaybackEngines\MetroSupport\Tools\AssemblyConverter.exe" -platform=wsa81 "C:\Users\Tomer\Documents\Unity Projects\bball_unity\Export\win8\Tabletop Basketball\\Assembly-CSharp.dll" "C:\Users\Tomer\Documents\Unity Projects\bball_unity\Export\win8\Tabletop Basketball\\UnityEngine.dll" "C:\Users\Tomer\Documents\Unity Projects\bball_unity\Export\win8\Tabletop Basketball\\WinRTLegacy.dll"
7. echo AssemblyConverter done.
8. " exited with code 1.    Tabletop Basketball
9.  

In the output log I see:

Code (CSharp):

21.  

Any ideas?
I checked and the file Assembly-CSharp-firstpass.dll is indeed in the directory that unity created.

 

It happened in Unity 4.5.3, and I just upgraded to 4.5.5, same result.

 

I'm using C# projects. I see it in both the unprocessed and root directory.
I did manage to narrow down the problem a bit. I'm using Unity Analytics, and although I encased all the code in

Code (CSharp):

1. if #UNITY_METRO

I still get these errors.

I found out that deleting a dll that was part of that plugin does solve the problem, but now I don't have that dll in non-metro builds either.

I also noticed that with the dll present, although the export succeeds, I'm getting a bunch of errors like this when exporting:

Code (CSharp):

1. Reference Rewriter: Error: field `System.Char System.IO.Path::DirectorySeparatorChar` doesn't exist in target framework. It is referenced from UnityEngine.Cloud.Analytics.dll at System.Void UnityEngine.Cloud.Analytics.SessionImpl::.cctor().
2.  
3. UnityEngine.Debug:LogError(Object)
4. PostProcessMetroPlayer:RunReferenceRewriter(MetroSDK, String, String, String, String) (at C:/BuildAgent/work/d63dfc6385190b60/PlatformDependent/MetroPlayer/Extensions/Managed/PostProcessMetroPlayer.cs:489)
5. PostProcessMetroPlayer:PostProcessSDKSpecific(MetroSDK, BuildTarget, BuildOptions, String, String, ProjectImages) (at C:/BuildAgent/work/d63dfc6385190b60/PlatformDependent/MetroPlayer/Extensions/Managed/PostProcessMetroPlayer.cs:1007)
6. PostProcessMetroPlayer:PostProcess(BuildTarget, BuildOptions, String, String, String, String) (at C:/BuildAgent/work/d63dfc6385190b60/PlatformDependent/MetroPlayer/Extensions/Managed/PostProcessMetroPlayer.cs:740)
7. UnityEditor.HostView:OnGUI()
8.  

Any help would be appreciated so I don't have to delete the dll every time I build for windows and re-add it when building for other platforms.

 

I'll give it a try, but just to be clear on what unity does when building to windows store:

If I have a plugin in Plugins\Metro, it would take that instead of the one in Plugins? And if I don't, then it uses the one in Plugins? (assuming both plugins have the same name)

 

An empty DLL seemed to do the trick.

Thanks!
