Clojure itself does not do any dependency management at all. For that you need Leiningen, which is clojure's build and dependency management tool, which can work with Maven repo's.

Steps:

1. install lein script
2. run lein self-install
3. do lein new <projectname> to create a new project in the current dir
4. go into the project dir and edit the project.clj file
5. add [org.apache.commons\commons-lang3 "3.4"] to the :dependencies vector
6. run lein repl to update the dependencies / get dependencies from local and start a repl of the project

Also, the (:import [org.apache.commons.lang StringUtils]) can only be used within the (ns ) block. Used outside of the ns block you should do a (import [org.apache.commons.lang StringUtils])
