lein is distributed as a standalone jar, which means a version of clojure and all other dependencies, is packaged with it. In addition, lein 1.7.1 is compiled against clojure 1.2.1, and would not be able to bootstrap using a future version. > So it seems that I have three different Clojures currently available but I > can't configure lein repl to use the latest one.

There are a set of tasks that do not read any information from the project.clj, version, help, and such. The repl task is allowed to run outside a project, but comes with the limitation that the classpath the repl uses will be the same as the classpath lein uses. This means for lein 1.7.1 it will use clojure 1.2.1, and for a recent lein 2.0.0-preview it will use clojure 1.4.0. When running the repl from a project lein is able to get the :dependencies desired, and use only those on the classpath. This is the way to use clojure 1.4.0 w/ lein 1.7.1. > what if I just want to start writing Clojure in an Emacs buffer without > having setup a lein project structure? Then the limitations above apply. I know some people when using lein 1.7.1 keep a project around with :dependencies [[org.clojure/clojure "1.4.0"]] and use it when doing quick repl interaction. I'd also like to note that nrepl.el[https://github.com/kingtim/nrepl.el] and swank-clojure[https://github.com/technomancy/swank-clojure] are the common ways to get emacs integration. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
