Now it seems that your command line is incorrect, see another thread:

Tasks support was removed after downloading plugin

Hi, Double-check your command line. You probably have an extra space somewhere in an argument so that it’s being read not as -Darg.key=argValue but as -Darg.key=arg totallyDifferentArg, and that second, ‘totallyDifferentArg’ is being interpreted as a task name (and indeed, tasks are no longer supported).   HTH, Ann

In your case, it could be due to "Sonar Scanner" which appears in sonar-scanner.bat "Sonar Scanner".
