No implementation of method: :as-file of protocol: #'clojure.java.io/Coercions found for class: clojure.lang.PersistentVector

Question

Getting a java.lang.IllegalArgumentException: No implementation of method: :as-file of protocol: #'clojure.java.io/Coercions found for class: clojure.lang.PersistentVector when i run lein test or lein repl from terminal on MAC OS X. Though lein repl works well in eclipse (with counterclockwise plugin)

Answer 1

The entry under :java-source-paths in your project.clj is a nested vector. It should be a plain vector of strings. Try replacing

:java-source-paths [["src/cmp/java"]]

with:

:java-source-paths ["src/cmp/java"]
