一、gradle地址
// https://mvnrepository.com/artifact/com.jcraft/jsch
compile group: 'com.jcraft', name: 'jsch', version: '0.1.54'
二、远程登录实例

三、一些涉及二次密码输入的情况
引入新的项目sshpass。
1. 下载及安装
$ wget http://sourceforge.net/projects/sshpass/files/latest/download -O sshpass.tar.gz
$ tar -xvf sshpass.tar.gz
$ cd sshpass-1.06
$ ./configure
# sudo make install
2. 使用示例
sshpass -p 'root123456' scp /home/test.txt root@192.168.4.125:/home
