Hello, Normally, just one of those file will have the (ns ). Others will just be (load)ed from the ns-defining file (the one with the (ns)), and contain just (in-ns 'echo.test) at their top. Then, just sending (compile 'echo.test) will compile everything. It's now that things get a little bit much complicated. Currently, if you just modify a secondary file of ns echo.test , then sending (compile 'echo.test) will not work, because the ns-defining file has not been modified, and so it will not be recompiled (because recompilation of the secondary file of ns echo.test is a side-effect of calling 'compile on the ns-defining file). The current solution to this problem in clojuredev is a brute-force one : 'touch all files to be sure that everything gets recompiled. There is currently a discussion on providing this behaviour in a cleaner way by using a global var or :reload-all flag to (compile). Using it, you will be sure that by calling (compile 'echo.test :reload-all true) on a namespace/lib, all the files being part of the ns will be recompiled, and you will not have to use 'touch trick anymore.
