As I come to know that LeeDavidPainter is the author of j2ssh plugin. I wanted to ask a question in which I am stuck on. I am trying to connect to a system using the j2ssh plugin with just IP and password. I see this stack trace:

I saw one of his posts in which he said this is out of date and I could use a new plugin by you which is J2SSH Maverick.
But when I used that I see the methods that I am using here are not compatible with the new plugin. SO Do I have to change the methods as well. I will show my code as well below.
import java.io.IOException;
import java.util.List;
import com.sshtools.j2ssh.SshClient;
import com.sshtools.j2ssh.authentication.AuthenticationProtocolState;
import com.sshtools.j2ssh.authentication.KBIAuthenticationClient;
import com.sshtools.j2ssh.authentication.PasswordAuthenticationClient;
import com.sshtools.j2ssh.transport.IgnoreHostKeyVerification;
public class checkThat {
public static void main(String s[])
{
try {
connect();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void connect() throws Exception {
try {
int result =-1;
String m_sUser= "user";
String m_sPassword="pswd";
SshClient ssh = new SshClient();
try{
ssh.connect("1.1.1.1", 22, new IgnoreHostKeyVerification());
}catch (IOException ie)
{
ie.printStackTrace();
}
//System.out.println( "Connect successful");
List authType = ssh.getAvailableAuthMethods(m_sUser);
if(!authType.isEmpty() && authType.contains("password"))
{
//m_logger.severe("FTSSH:Connected to host via password");
PasswordAuthenticationClient pwd = new PasswordAuthenticationClient();
pwd.setUsername(m_sUser);
pwd.setPassword(m_sPassword);
// Authenticate the user
result = ssh.authenticate(pwd);
}
else
{
//m_logger.severe("FTSSH:Connected to host via KBI");
KBIAuthenticationClient kbi = new KBIAuthenticationClient();
kbi.setUsername(m_sUser);
/*ASCKBIRequestHandler kbiHandler = new ASCKBIRequestHandler();
kbiHandler.setPassCode(m_sPassword);
kbi.setKBIRequestHandler(kbiHandler);*/
// Authenticate the user
result = ssh.authenticate(kbi);
}
/* Authenticate.
* If you get an IOException saying something like
* "Authentication method password not supported by the server at this stage."
*/
PasswordAuthenticationClient pwd = new PasswordAuthenticationClient();
pwd.setUsername("user");
pwd.setPassword("pswd");
result = ssh.authenticate(pwd);
if (result != AuthenticationProtocolState.COMPLETE){
throw new Exception("Login to failed");
}
/*session = ssh.openSessionChannel();
sor = new SessionOutputReader(session);
// Request a pseudo terminal, if you do not you may not see the prompt
session.requestPseudoTerminal("gogrid",80,48, 0 , 0, "");
// Start the users shell
session.startShell();*/
} catch (Exception e) {
//log.error(e.getMessage(), e);
System.out.println( e.getMessage());
e.printStackTrace();
throw new Exception("Login to failed");
}
}
}
So here if I change the .jar file from j2ssh to j2ssh maverick, the methods such as sshClient, ignoreHostKeyVerification, PasswordAuthenticationClient, etc. are not resolved.
What could be the issue?
