Re: Exception: clojure.lang.ExceptionInfo thrown from the UncaughtExceptionHandler in thread "main"

I did not touch the  ~/.lein/profiles.clj file. 

I got things to work by removing everything related to Timbre. I would 
guess that I had some kind of naming class between Timbre and 
clojure.tools.logging. I decided to just use clojure.tools.logging, and 
that seems to have fixed the problem.

RE: Exception: clojure.lang.ExceptionInfo thrown from the UncaughtExceptionHandler in thread "main"

2018-12-24 Thread Sean Corfield 
Did you change your ~/.lein/profiles.clj file? That’s the most common cause of 
mysterious startup failures with Leiningen it seems. Try removing/renaming that 
file and see if your problems go away.

If you have more of the stacktrace to share (via pastebin or a gist etc), that 
might help folks offer suggestions.

Subject: Exception: clojure.lang.ExceptionInfo thrown from the 
UncaughtExceptionHandler in thread "main"

I'm not sure what I did, but suddenly I'm getting this:

Exception: clojure.lang.ExceptionInfo thrown from the UncaughtExceptionHandler 
in thread "main"

Exception: clojure.lang.ExceptionInfo thrown from the UncaughtExceptionHandler 
in thread "Thread-0"

I had been using println to do some debugging, but then I added :

 [com.taoensso/timbre "4.10.0"]

I think that is the last think I did. Then I did:

lein uberjar

And then I tried to run that from the command line.

I've added a bunch of logging to try to get a stacktrace, but none of this is 
working so far:

(defn -main [& args]

  (slingshot/try+

   ;; 2017-10-04 -- see this:
   ;; 
https://stackoverflow.com/questions/28908835/ssl-peer-shut-down-incorrectly-in-java
   (System/setProperty "https.protocols" "TLSv1.1")

   (.addShutdownHook (Runtime/getRuntime)
 (Thread.
  #(do (error "addShutdownHook triggered. This app is 
shutting down.")
   (stop

   ;; 2017-07-12 -- stealing code from here:
   ;; https://stuartsierra.com/2015/05/27/clojure-uncaught-exceptions
   ;; Assuming require [clojure.tools.logging :as log]
   (Thread/setDefaultUncaughtExceptionHandler
(reify Thread$UncaughtExceptionHandler
  (uncaughtException [_ thread ex]
(log "the app has died ")
(log ex)
(log "Uncaught background exception on thread " (.getName thread) " 
Caught by Thread/setDefaultUncaughtExceptionHandler in core/main.")
(System/exit 1

   (slingshot/try+
(start)
(catch Exception e
  (stack/parse-exception e)
  (log (str e))
  (log "the app has died!")
  (System/exit 1))
(catch Throwable t
  (log t)
  (log "the app has died!")
  (System/exit 1))
(catch Object o
  (log o)
  (log "the app has died!")
  (System/exit 1)


And yet all I get is:

Exception: clojure.lang.ExceptionInfo thrown from the UncaughtExceptionHandler 
in thread "main"

Exception: clojure.lang.ExceptionInfo thrown from the UncaughtExceptionHandler 
in thread "Thread-0"

Somehow the other lines that I try to print never get called. Nor my call to my 
log function which should give me a stacktrace.

What is the obvious thing to do here?
