it seems you can't use string'ed arguments in this action like:

MyCmd.cmd "my string param"

Build log says:

The action that was executing threw an exception that was not handled.

Exception: ArgumentException Message: Illegal characters in path. Stack Trace: at System.IO.Path.CheckInvalidPathChars(String path) at System.IO.Path.GetExtension(String path) at Continua.Modules.Builds.Stepping.Actions.RunDosCommandAction.GetCommandLine(IBuildSteppingContext context) at Continua.Stepping.Actions.ExecuteAction`1.Execute(TContext context)

if i remove them its working but for sure, they args of my command are wrong.
