Java and Clojure with Leiningen
As of Leiningen 2.x, :java-source-path has been replaced with :java-source-paths, whose value is now specified as a vector rather than a string. A good place to find a full (up-to-date) documentation of Leiningen features is to peruse the sample project file. In this case, you will see: :java-source-paths [“src/main/java”]
