`Error loading cemerick.piggieback` when launching `lein repl` on projects created with 0.5.16 #689

Closed bjonica closed 6 years ago

bjonica commented 6 years ago

This wasn't an issue on 0.5.15, and strangely enough lein figwheel works, but when I launch lein repl on a fresh project, I get the following errors:

Error loading cemerick.piggieback: Could not locate cemerick/piggieback__init.class or cemerick/piggieback.clj on classpath.

Project was generated with lein new figwheel hello-world -- --reagent, java 9.0.1. I tried clearing .m2/repositories to no avail.

Found the culprit and workaround. The generated project.clj has :repl-options {:nrepl-middleware [cemerick.piggieback/wrap-cljs-repl]}. Changing this to cider.piggieback matches the pulled in dependency and gets the project working again.
