Issue Phenomenon :

In Jenkins Update Center , There are display two the same duplicated items for this plugin - SSH2 Easy Plugin V1.3 .

Root Cause :
It is rename (ID : ssh2easy ) to another with suffix -plugin (new ID : ssh2easy-plugin) and release again by the author of this plugin .

Resolved :
Now remove the ssh2easy-plugin from update center , just leave ssh2easy only available .

To Users:
1. If you has already install the ssh2easy-plugin , You can find the SSH2 Easy Plugin still there in available for installation , I suggest you uninstalled SSH2 Easy Plugin and re-install from available for installation tab again . Then it will keep update in future . Sorry for this changes with this issue .
