Michael Osipov commented on WAGON-446:
--------------------------------------

Apologies not responding anytime earlier. Still is still on track, but requires a significant amount of time to complete and especially test I don't have at the moment. Since this is also a breaking change I recommend to move this to the next major version.

> After upgrading to wagon-2.10,  SSH Agent authentication doesn't seems to work anymore. I got the following error when trying to publish a site, using maven-site-plugin 3.4:
> Using private key: <PATH TO id_rsa>
> : Error uploading site: Cannot connect. Reason: Auth fail -> [Help 1]
> I have no server for this site defined in my settings.xml
> After some investigation, I suspect that the cause is WAGON-413 since the  logic in AbstractJschWagon was changed to not use the agent if ScpHelper.getPrivateKey() returns a File. 
> Unfortunate, ScpHelper.getPrivateKey() seems to have a fallback behavior that always returns the id_rsa key (if one exists) even when no matching server element exists in settings.xml and the effect is that the agent is never consulted. 
> The authentication will then fail since no server element provides a key password.
> My current workaround is to set the wagon.privateKeyDirectory System Property to an empty directory. This will prevent the ScpHelper.getPrivateKey() fallback to kick in.
> Has anybody else got SSH agent working in combination with existing id_rsa files?
