Leiningen actually isn't that far from being exactly that. It's not a one-liner, but setting up a scratch project that'll give you a repl is very straightforward. Setting up swank is only slightly less simple because you've got to edit a config file. It can be difficult to figure out the right incantation for that because the docs are pretty nonexistent, but google is helpful enough there.
