------------------------------------------

             Summary: Upgrade jsch dependency to 0.1.51 or newer to support ECDSA host key typess
                 Key: WAGON-464
                 URL: https://issues.apache.org/jira/browse/WAGON-464
             Project: Maven Wagon
          Issue Type: Wish
          Components: wagon-ssh
    Affects Versions: 2.10
            Reporter: Christof Schablinski


If public keys in known_hosts file are saved in a ECDSA (ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521) format, Maven will fail with the little helpful message:

{code}
Unable to create a Wagon instance for host foo.bar.lan
{code}

Switching on debug mode will tell you this, but not the root cause:

{code}
