I updated to Cap 3 and it appears that set :deploy_via, :copy is no longer supported. In the release annoucement there is a link to a video for replicating the copy
set :deploy_via, :copy
You can use its gem - https://github.com/WildZero/capistrano-scm-tar-copy
set:
set :scm, :copy
set :include_dir, '/User/w1ldzer0/ExampleDir'
and go
