Description

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:

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

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