java -jar standalone.jar throws ExceptionInInitializerError - Caused by: j.l.ClassCastException: c.l.Var$Unbound cannot be cast to clojure.lang.MultiFn

tangrammer opened this issue 7 years ago · comments

I'm a bit lost having this problem only when i tried my app using the uberjar generated using lein uberjar

The error says ...
Caused by: java.lang.ClassCastException: clojure.lang.Var$Unbound cannot be cast to clojure.lang.MultiFn

(perhaps) Could be related with my AOT project.clj config???

:main roc.platform.main
:aot [roc.platform.main
          #"roc\.platform\.*" 
          #"roc\.[a-z]+$"]

the output error ...

You might try adding automat to your AOT compilation, or just do :aot :all, which is what I always do.

Juan A. Ruz · Answer 2 · Thu Jun 08 2017 19:56:53 GMT+0800 (China Standard Time)

Hi Zach
Adding :aot :all didn't fix the error yet so I was investigating a bit trying to isolate the problem so maybe could be more fixable now

I uploaded a minimal project here https://github.com/tangrammer/automat-issue
It has 3 branchs trying to be easier to test every odd isolated case

simple working case: origin/master branch commit
main namespace works fine when i execute lein clean && lein uberjar && java -jar target/issue-0.1.0-SNAPSHOT-standalone.jar
simple failing one: origin/fails-00 branch commit
I only add one dep [com.cemerick/url "0.1.1"] and execute again lein clean && lein uberjar && java -jar target/issue-0.1.0-SNAPSHOT-standalone.jar
comenting (:require [automat.core :as a]) fix the problem origin/now-works branch commit
Removing/comenting the automat namespace required fix the problem
(Following this odd trick i don't know how to use the lib in other namespaces )

Thanks a lot again!

Searching for this problem in the context of clojurescript i found this discussion that links to this CLJ-1591
Symbol not being bound in namespace when name clashes with clojure.core

BTW: error happens with other deps like [bidi "1.21.0"] or [selmer "0.9.4"] or [cljs-react-material-ui "0.2.37"]

Including error got when compiling issue.hola.clj

@deprecated comment ... just realised that bidi [bidi "1.21.0"] uses [com.cemerick/url "0.1.1"] that i previously noted that is a dep failing one

@ztellman maybe this info could help too

bidi 2.1.1 => works

 :dependencies [[org.clojure/clojure "1.8.0"]
                 [automat "0.2.2"]
                 [bidi "2.1.1"]]

bidi 1.21.0 fails

  :dependencies [[org.clojure/clojure "1.8.0"]
                 [automat "0.2.2"]
                 [bidi "1.21.0"]]

https://github.com/juxt/bidi/blob/1.21.0/project.clj

really sorry for the noise but i'm really in trouble deploying prod app :()

If anyone could point me any reasons to start with solving this issue i'll really appreciate it

Thanks again

Juan A. Ruz · Answer 5 · Fri Jun 09 2017 20:06:19 GMT+0800 (China Standard Time)

Hi again,
looking at deps and nested deps I realised that clojurescript was always present in problematic libs . I' tried to avoid the problem adding org.clojure/clojurescript to exclusions and surprisingly it fixed the problem

:exclusions [org.clojure/clojurescript]

I also had to remove clojurescript from :dependencies vector :!

Feel free to close the issue if you think the error doesn't relate to automat

thanks and sorry for so much noise!
