The current version of the chef development kit (2.3.4) installs a much newer version of the chef gem (13.4.19) which lacks the following files required by your knife plugin:
/opt/chefdk/embedded/lib/ruby/gems/2.4.0/gems/chef-13.4.19/lib/chef/monkey_patches/net-ssh-multi.rb
/opt/chefdk/embedded/lib/ruby/gems/2.4.0/gems/chef-13.4.19/lib/chef/mixin/command.rb
I have been able to get the plugin running by removing the "requires" lines for the above files, but I do not know what functionality will break by having done so.
