reject HostKey: bitbucket.org

Hi There, 

I have tried to access bitbucket repo programmatically through ssh. It throws following error.

If I try ssh -v git@bitbucket.org. It adds to known hosts then it started working.

"Warning: Permanently added 'bitbucket.org,104.192.143.1' (RSA) to the list of known hosts"

Is it mandatory to add bitbucket to known hosts to access bitbucket via ssh?

You can disable host key check by adding this configure method to your  JschConfigSessionFactory class:

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