With the current project configuration clojurescript is pulled in as a dependency by default into pure clojure projects

[imrekoszo]

Take the following minimal deps.edn:

{:deps {org.clojure/clojure {:mvn/version "1.8.0"}
        traversy/traversy   {:mvn/version "0.5.0"}}}

Clojurescript will show up as a hard dependency despite it not even being referenced in any production code paths in traversy itself:

> clojure -Stree
org.clojure/clojure 1.8.0
traversy/traversy 0.5.0
  org.clojure/clojurescript 0.0-3308

      com.google.code.gson/gson 2.2.4
    org.clojure/tools.reader 0.9.2

It is possible I'm missing something here, nevertheless I am going to submit a pull request to try and address this.
