Cursive requires a project.clj file to infer some important information. Adding a lein-generate task as the one below can generate a project.clj file on the fly so Cursive knows what to do.

(defn- generate-lein-project-file!
  [& {:keys [keep-project] :or {:keep-project true}}]
  (let [pfile (io/file "project.clj")
        pname (or (get-env :project) 'boot-project)
        pvers (or (get-env :version) "0.1.0-SNAPSHOT")
        prop #(when-let [x (get-env %2)] [%1 x])
        head (list* 'defproject pname pvers
               (concat
                 (prop :url :url)
                 (prop :license :license)
                 (prop :description :description)
                 [:dependencies (get-env :dependencies)
                  :source-paths (vec (get-env :source-paths))]))
        proj (pp-str (concat head (mapcat identity (get-env :lein))))]
    (if-not keep-project (.deleteOnExit pfile))
    (spit pfile proj)))

(deftask lein-generate
  "Generate a leiningen `project.clj` file.
  This task generates a leiningen `project.clj` file based on the boot
  environment configuration, including project name and version (generated
  if not present), dependencies, and source paths. Additional keys may be added
  to the generated `project.clj` file by specifying a `:lein` key in the boot
  environment whose value is a map of keys-value pairs to add to `project.clj`."
  [] (generate-lein-project-file! :keep-project true))
