我在我的java类中运行下面的代码，理想情况下它应该返回一个承载令牌..
下面是我运行的代码：

String[] command = {"curl","-v","-
X","POST","https://<Domain name>/oauth2/token","-H","cache-control: 
no-cache","-H","content-type: application/x-www-form-urlencoded","-
H","postman-token: a1f5e569-cbc7-63cc-8667-45d85d74784b","-d","client_id=XXXXXXX","&","client_secret=XXXXXXXXXX","&","grant_type=client_credentials"};
for (String s: command)
            System.out.print(s); 
        ProcessBuilder process = new ProcessBuilder(command);
         Process p;
try {
                p = process.start();
     }

字符串
我得到的例外是
java.io.IOException：Cannot run program“curl”：无法运行程序“curl”：进程错误=2，系统找不到指定的文件
有人能告诉我问题是什么或者如何从JAVA运行curl命令吗？
