I'm trying to build NuGet solution on TeamCity. I'm using the Build\Build.proj as a build file in MSBuild step.
The build keeps failing in following step
[Build\Build.proj.teamcity] VerifyAssembliesInVSIX
  [VerifyAssembliesInVSIX] Exec
    [Exec] EXEC 
    [Exec] C:\TeamCity\buildAgent\work\75db8d2c948fd757\Build\Build.proj(173, 9): error MSB3073: The command ""C:\TeamCity\buildAgent\work\75db8d2c948fd757\Build\..\Tools\7za920\7za.exe" x -o"C:\TeamCity\buildAgent\work\75db8d2c948fd757\Build\..\bin\Temp" "C:\TeamCity\buildAgent\work\75db8d2c948fd757\Build\..\src\VsExtension\bin\Debug\NuGet.Tools.vsix"" exited with code 2.
[Build\Build.proj.teamcity] Project Build\Build.proj.teamcity failed.
I checked the log and it looks like the VsExtension project is not built and therefore the vsix file is never created.
Can anyone help me?
