Using StrictHostKeyChecking=false with maven3

[mickael leduque <mi...@gmail.com>]

Hello,

I'm trying to use wagon-ssh with StrictHostKeyChecking set to false with
maven 3 (non interactive upload).

All answers to the same question seem to advise to  do something like

<server>
  <id>deploy.host</id>
  <configuration>
    <knownHostsProviderimplementation="org.apache.maven.wagon.providers.ssh.knownhost.NullKnownHostProvider">

      <hostKeyChecking>no</hostKeyChecking>
    </knownHostsProvider>
  </configuration>
</server>

Anyway, something seems to have broken with maven3 :

[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-site-plugin:3.0:deploy (default-deploy) on
project csFmkParent: Unable to configure Wagon: 'scp': While configuring

I can"t find an existing issue about this (thought it is mentioned in the
last comment for MSITE-546). Am I right this is an issue with maven 3 ?
