Unable to connect using SSH in JGit [message #1829533]

Hi,

I am trying to connect to github.com using SSH and JGit. This is the code I am trying:-
public static void gitClone(File gitDirectoryPath) throws Exception {
SshSessionFactory sshSessionFactory = new JschConfigSessionFactory() {
@Override
protected void configure(OpenSshConfig.Host host, Session session) {
session.setUserInfo(new UserInfo() {
@Override
public String getPassphrase() {
return "";
}

@Override
public String getPassword() {
return null;
}

@Override
public boolean promptPassword(String message) {
return false;
}

@Override
public boolean promptPassphrase(String message) {
return true;
}

@Override
public boolean promptYesNo(String message) {
return false;
}

@Override
public void showMessage(String message) {
}
});
}
};

Git.cloneRepository().setTransportConfigCallback(new SshTransportConfigCallback()).setURI("git@github.com:agarwalvipul/core-java-template.git")
.setDirectory(gitDirectoryPath).call();

}

private static class SshTransportConfigCallback implements TransportConfigCallback {
private final SshSessionFactory sshSessionFactory = new JschConfigSessionFactory() {
@Override
protected void configure(OpenSshConfig.Host hc, Session session) {
session.setConfig("StrictHostKeyChecking", "no");
}
};

@Override
public void configure(Transport transport) {
SshTransport sshTransport = (SshTransport) transport;
sshTransport.setSshSessionFactory(sshSessionFactory);
}
}

I am getting the following exception:-

Can anyone help me in this context?

Hi All,

I'm facing the same issue while trying to pull through SSH in jgit.
The key files are correct, double checked it.

SshSessionFactory sshSessionFactory = new JschConfigSessionFactory() {
@Override
protected void configure(OpenSshConfig.Host host, Session session) {
session.setConfig("StrictHostKeyChecking", "no");
}
....

I'm setting this sessionFactory.

pull.setTransportConfigCallback(transport -> ((SshTransport)transport).setSshSessionFactory(sshSessionFactory));

Kindly advice how to proceed.

We don't recommend the old jsch integration [1], use the integration for the mina-sshd client [2] instead.
You can start digging from JGit's unit tests for its integration with the mina-sshd client [3].
