Answer 1

ProcessBuilder不使用完整的命令行，例如

ProcessBuilder b = new ProcessBuilder("cmd /c C:\Windows\System32\winrs.exe -r:http://ipaddress:port -u:username -p:password dir");

但需要將可執行文件和參數分開：

ProcessBuilder b = new ProcessBuilder("cmd", "/c", "C:\Windows\System32\winrs.exe", "-r:http://ipaddress:port", "-u:username", "-p:password", "dir");
