Java doesn’t allow – in names. That’s why Clojure and Clojure tooling maps – in names to _ in files (and classes).

It looks like 'lein uberjar' and 'lein jar' don't like namespace path elements that contain hyphens. Example: lein new app foo-bar cd foo-bar Now edit src/foo_bar/core.clj, changing (ns foo-bar.core (:gen-class)) to (ns foo-bar.core (:gen-class :name foo-bar.core)) Then 'lein uberjar' reports: Compiling foo-bar.core Warning: The Main-Class specified does not exist within the jar. It may not be executable as expected. A gen-class directive may be missing in the namespace which contains the main method. Also, 'java -jar target/uberjar/foo-bar-0.1.0-SNAPSHOT-standalone.jar' prints: Error: Could not find or load main class foo_bar.core A similar problem seems to occur with 'lein jar'. However, no problem occurs with 'lein run', or with 'lein uberjar' if :name is left out of the ns form, or if :name is used but the project namespace qualifier does not contain a hyphen. I think this has to do with the fact that when I use :name with foo-bar, core.class ends up in target/uberjar/classes/foo-bar, while its related inner class files end up in target/uberjar/classes/foo_bar. If I don't use :name or if the path doesn't contain a dash, all of the classes end up in the same directory, e.g. foo_bar. (I don't know much about jar files or subtleties of how the jvm interprets them.) I have a standalone project that runs fine with 'lein run' but I'm unable to make an uberjar because of this problem. (I apparently to need the :name element in order to create an instance of the same class in my -main function.) The project is small enough that it won't be much trouble to rename filenames and namespace paths in order to get rid of dashes, but I'm wondering if there's a different solution. I'm also wondering whether this is a bug/flaw in Leiningen. I can submit an issue if so. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
