wagon ssh corrupts known_hosts?

I have a step release process.

Step 1 uses maven and the wagon-ssh plugin to push .debs and .jars to my
maven and debian repositories via SSH and the scp:// wagon which uses jSch.

Step 2 uses ansible and SSH via OpenSSH… this is the step that breaks now
because jSch writes a new known_hosts file. SSH then prompts me every time
to accept the new host key.

This is prone to error and I want to fix it.. I do releases in ‘screen’
and if I forget to come back 5 minutes later to type ‘yes’ for all my hosts
it breaks the release.

Plus I want it automated for obvious reasons.
