Rails Net::SCP file transfer -

i have rake task set fetch folder remote server using nets/scp gem. gemfile:

gem "net-ssh" gem "net-scp" 

my code:

require 'net/scp' desc "fetch hadoop data" task :fetch_data => :environment  net::scp.download!("server_name", "user",   "/home/dashboard/data", "#{rails.root}/lib/tasks",   :password => "password1") end 

i error:scp did not finish (1)

how save folder rails tasks directory, , how can print out more informaiton causing scp error? also, have id_rsa key saved in know

i ended using different method scp file over:

require 'net/ssh' require 'net/scp'    desc "fetch hadoop data"   task :fetch_data => :environment     date_yesterday = (datetime.now - 1.days).strftime("%y%m%d")     date_today = (datetime.now).strftime("%y%m%d")     net::ssh.start("server_name", "user",:password => "*****") |session|       session.scp.download!("path_to_file_on_remote", "/home/rails_app/lib/tasks/folder",  :recursive => true)     end   end
