MSBuild is being invoked and ends up hanging the step. This is the command-line that QB is invoking:
14:18:35,018 DEBUG - Executing command: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe /nologo /noconsolelogger /l:QBLogger,D:\qb_installer\framework\configuration\org.eclipse.osgi\com\pmease\quickbuild\plugin\builder\msbuild\PMEase.QuickBuild.MSBuild.Logger.dll;v=detailed /p:IIF_ProductVersion=10.0.0 D:\qb\workspacePath\Product.proj
The log output looks normal until it starts displaying the following:
14:18:37,083 INFO - QB_LOGEVENT:MESSAGE_RAISED:Normal
It displays 140 of these lines in less than a second then hangs. If I invoke the exact command-line that QB is using in a command-window, it hangs in the same manner and the command-window has to be closed.
If I alter the command-line to omit the QB logger, the MSBuild command executes normally and takes only 2-3 seconds.
