I am using sonar-runner and try to parse my C# solution. The coverage tool that I use for Gallio is OpenCover (Although I am getting the same exception with dotCover). I have the following two problems:

1- This problem: http://stackoverflow.com/questions/10519558/createprocess-error-206-the-filename-or-extension-is-too-long-when-running-main
The parameters that are passed to OpenCover are too long. I tried to decrease the path length by creating a junction from C:\s to source folder but it didn't help.

Exception in thread "main" org.sonar.runner.RunnerException: org.sonar.api.utils.command.CommandException: java.io.IOException: Cannot run program "C:\Program Files\OpenCover\OpenCover.Console.exe" (in directory "F:\VP\playpens\development\subversion\MyLovelyProjectFolder\.sonar"): CreateProcess error=206, The filename or extension is too long

The command that is tried to be executed is the following:

16:17:47.593 INFO .u.c.CommandExecutor - Executing command: C:\Program Files\OpenCover\OpenCover.Console.exe -register:user -target:C:\Program Files\Gallio\bin\Gallio.Echo.exe -targetdir:F:\VP\playpens\development\subversion\MyLovelyProjectFolder\.sonar "-targetargs:\"/r:IsolatedAppDomain\" \"/report-directory:F:\VP\playpens\development\subversion\MyLovelyProjectFolder\.sonar\" \"/report-name-format:gallio-report\" \"/report-type:Xml\"
\"assembly1.dll"
\"assembly2.dll"
....
\"assemblyN.dll"
-output:F:\VP\playpens\development\subversion\MyLovelyProjectFolder\.sonar\coverage-report.xml

What do you advise me to do?

2- When I enable the StyleCop plugin, it is throwing the following exception:

I see similar errors related to path length:

Note: I tried to access the user email list to describe this problem first but was unable to send an email although I have subscribed to the list.
