No matching method found: put for class com.jcraft.jsch.ChannelSftp

Hey this is my first time using this library, ive heard pretty good things about it.

I am trying to execute the following command:

`(sftp "host" :put file "/" :username "user" :password "password" :port port_no)`

but the following error gets thrown:

`No matching method found: put for class com.jcraft.jsch.ChannelSftp`

if i manually execute `sftp` from the command line and type the password all works as expected, however I can't figure out why this isn't working.

I am using version `0.5.11` hopefully its something trivial.
