reload-clojure causes compilation failure in portable projects

[cemerick]

Given a project that is attempting to provide a portable API for both Clojure and ClojureScript, any overlapping aliases in conjunction with lein-cljsbuild's reload-clojure function will produce a ClojureScript compilation failure.

In short, reload-clojure loads any Clojure files that are on its :source-paths, and because the ClojureScript compiler reuses the Clojure reader, the former creates any namespaces that have aliases defined, in order for the latter can properly resolve namespaced keywords. So, if Clojure and ClojureScript files are on lein-cljsbuild's :source-path that create analogous namespaces with identical aliases (roughly unavoidable if one is using a tool like cljx or lein-dalap to produce a portable API), ClojureScript compilation will always fail.

A minimal testcase is available here.

A partial "fix" would be to have reload-clojure be called only if lein-cljsbuild is in "auto" mode, watching for source changes, but perhaps there's a smarter, more general solution?

+1 I just got burned by this too

This issue seems to be resolved as of clojurescript 2202 and is certainly not present in the current release 2411. There is no longer a need to not reload non macro .clj files in cljs source directories.
