I have bellowing example:
```org
#+NAME: read-in-wxid
#+begin_src clojure :var cwd=(file-truename "~/Documents/WeChat/wxid/")
(require '[
clojure.java.io :as io])
(def directory (io/file cwd))
(def files (filter #(.isFile %) (file-seq directory)))
#+end_src
#+RESULTS[<2019-08-28 09:12:24> 84a1210d836742ca71ddddc776aaebba0e0224af]: read-in-wxid
: #'user/files
#+begin_src clojure :noweb yes :results pp
<<read-in-wxid>>
(take 3 files)
#+end_src
#+RESULTS[<2019-08-28 09:12:30> 9bbcd9f779f72bdd9b7bb8fb85aa36bbdfee7e3c]:
: class clojure.lang.Compiler$CompilerExceptionclass clojure.lang.Compiler$CompilerExceptionSyntax error compiling at (*Org Src Code.org[ clojure ]*:3:16).

```
You can see it can't resole first source block's `:var` definition.
