JGit - ssh connectivity - ssh

Question

I am using JGit to connect to a remote Git repository. I tried below to perform same.
public class Main{
public static void main(String args[]) throws Exception{
JschConfigSessionFactory sshSessionFactory = new JschConfigSessionFactory() {
#Override
protected void configure( Host host, Session session ) {
session.setPassword( "XXXX" );
}
};
String REMOTE_URL="ssh://git#url/test.git";
CloneCommand cloneCommand = Git.cloneRepository();
cloneCommand.setURI( "ssh://git#url/test.git" );
cloneCommand.setTransportConfigCallback( new TransportConfigCallback() {
#Override
public void configure( Transport transport ) {
SshTransport sshTransport = ( SshTransport )transport;
sshTransport.setSshSessionFactory( sshSessionFactory );
}
} );
System.out.println("Listing remote repository " + REMOTE_URL);
Collection<Ref> refs = Git.lsRemoteRepository()
.setHeads(true)
.setTags(true)
.setRemote(REMOTE_URL)
.call();
for (Ref ref : refs) {
System.out.println("Ref: " + ref);
}
}
}

I looked over internet; and found that, below needs to be added:
com.jcraft.jsch.JSch.setConfig ( "StrictHostKeyChecking", "no" );
But, where to fit it in above code snippet. Is there any sample working code snippet available.

Answer 1

You can call setConfig("","") method using Session object as shown below:-
JSch jsch = new JSch();
Session session = jsch.getSession(username, hostname, 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword(password);
session.connect();
Hope that helps.
