<blockquote>
<p>See <a href="http://sial.org/howto/openssh/publickey-auth/">OpenSSH Public Key Authentication</a></p>
</blockquote>
<p>If you get hung up during release:perform because Maven can’t verify the authenticity of a host, then there could be
one of two different problems. The first problem, which is an easy fix, is to go to the command line and use SSH
to log in to that host. You should receive a prompt to add the host to your known_hosts file. If you add the host
to your <code class="highlighter-rouge">known_hosts</code> file from the command line SSH, then you should be able to try <code class="highlighter-rouge">release:perform</code> again
and have more success. There is a chance though that this won’t fix maven.</p>
<p>Maven doesn’t appear to understand hashed <code class="highlighter-rouge">known_hosts</code> files. There is some information here - <a href="http://itso.iu.edu/Hashing_the_OpenSSH_known__hosts_File">known_hosts file Hashing</a>.</p>
<p>If your <code class="highlighter-rouge">known_hosts</code> file is hashed, you can solve this one of a few different ways. If you perform a <code class="highlighter-rouge">deploy:deploy</code>
instead of <code class="highlighter-rouge">release:perform</code>, then maven will leave a prompt open for you to type <code class="highlighter-rouge">yes</code> and have maven add the host
(in a way that Jsch, the library which provides Maven Wagon with the SSH/SCP functionality, understands)
to your <code class="highlighter-rouge">known_hosts</code> file. Another option is to remove your <code class="highlighter-rouge">known_hosts</code> file, update your SSH configuration so that
it does not hash the hostname in <code class="highlighter-rouge">known_hosts</code> and try to log in from the command line.</p>
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>mkdir ~/.ssh
