Getting Launcher instance in Descriptor of builder

[Nikhil Bhoski]

I am trying to verify if the given path is valid on the system. User in put is String value . i do check this by invoking docheck methods in builder descriptor. 

However i cant use Jenkins.getInstance().getChannel() as it returns null is i am checking the path on remote slave . do any one know how can i get the Launcher instance or Virtual channel instance of Remote slave in Descriptor of Builder .

No, this is not possible. How would you know in advance what agent is
going to perform any build? It could change from build to build, and
the agent might not even exist yet.
