SSH shell异常

Question

线程“main”java.lang.NoClassDeffounder中出现异常错误：org/apache/commons/io/input/NullinPutStream at main.main（main.java：6）原因：java.lang.ClassNotFoundexception：org.apache.commons.io.input.NullinPutStream at java.net.urlClassLoader.findClass（urlClassLoader.java:381)at java.lang.ClassLoader.LoadClass（classLoader.java:424)at

代码：

import com.jcabi.ssh.SSH;
import com.jcabi.ssh.Shell;

class Main{
    public static void main(String[] args) throws Exception{
        String hello = new Shell.Plain(
                new SSH(
                        "192.168.1.19", 22,
                        "pi", "raspberry"
                )
        ).exec("echo 'Hello, world!'");
    }
}

您似乎将用户名和用户密码作为参数发送，但根据文档，该库需要RSA密钥。

使用SSHByPassword

http://ssh.jcabi.com/apidocs-1.5/com/jcabi/ssh/sshbypassword.html

private String address;
private int port;
private String user;
private String password;

/**
 * @param address - server IP
 * @param port - SSH port
 * @param user - login user
 * @param password - user password
 */

public SSHcommunicator(String address, int port, String user, String password) {
    this.address = address;
    this.port = port;
    this.user = user;
    this.password = password;
}

public String sayHello() throws IOException {

    Shell shell = new SSHByPassword(address, port, user, password);
    return new Shell.Plain(shell).exec("echo 'Hello, world!'");
}
