The problem seems to be (lm-version) doesn't have the buffer available when clojure-mode.el is being executed (loaded).

The following code works for me

(defconst clojure-mode-version
  (with-current-buffer (find-file-noselect "~/.emacs.d/elpa/clojure-mode-20190105.1043/clojure-mode.el")
    (lm-version))
  "The current version of `clojure-mode'.")

So this works too:

(defconst clojure-mode-version
  (with-current-buffer (find-file-noselect load-file-name)
    (lm-version))
  "The current version of `clojure-mode'.")

And using something like (or load-file-name buffer-file-name) it can work also when visiting the buffer.

If loading, the buffer would have to be closed afterwards. Otherwise Emacs starts with a clojure-mode.el buffer open !

Should I submit a PR with these changes, or with a simple constant (dropping (lm-version)) ?

This issue still persists, the problem occurs when emacs loads the byte compiled file clojure-mode.elc. If it is deleted and emacs loads clojure-mode.el, it works.
