Thank you very much for the suggestion. I believe that your diagnosis is correct; unfortunately, your solution does not work. Furthermore, even if I remove the dependency on clj-jgit and all references to it from my code, do a 'lein clean', and rebuild, I still get the same error on startup (although my application does start and run, which it didn't before).
What does work is if I clone scm-jgit, update its dependency to [org.clojure/core.memoize "0.5.6"] and its version to '0.8.2-SNAPSHOT', build it with 'lein install', and then build my own application, then everything works fine. I can't really, though, distribute a project based on an unsupported version on someone else's project. I'll try sending a project.clj diff to the maintainers of clj-jgit, and see if they'll accept it. This feels remarkably like DLL Hell :-( On Thursday, 13 November 2014 22:56:17 UTC, James Reeves wrote: > > The problem is that your dependency tree pulls in core.memoize 0.5.3, but > other libraries have a dependency on 0.5.6.
