Specifying TIMBRE_LEVEL can cause tools.deps to crash

[ivarref]

Hi,

and thanks for a fine library!

It seems that specifying TIMBRE_LEVEL can cause tools.deps to crash. I'm using the latest homebrew Clojure version, 1.10.1.466.

File to reproduce the behaviour:

#!/usr/bin/env bash

set -ex

echo '(ns main) (defn -main [& _] (println "Hello world"))' > main.clj
echo '
{:paths ["."]
 :deps {com.taoensso/timbre        {:mvn/version "4.10.0"}
        com.fzakaria/slf4j-timbre  {:mvn/version "0.3.14"}
        org.slf4j/log4j-over-slf4j {:mvn/version "1.7.14"}
        org.slf4j/jcl-over-slf4j   {:mvn/version "1.7.14"}
        org.slf4j/jul-to-slf4j     {:mvn/version "1.7.14"}
        pack/pack.alpha            {:git/url    "https://github.com/juxt/pack.alpha.git"
                                    :sha        "9911c70bcfd6e94383d3d54b6e8befa492222926"
                                    :exclusions [org.slf4j/slf4j-nop]}}}' > deps.edn

clojure \
-J-DTIMBRE_LEVEL=warn \
-Sverbose \
-m mach.pack.alpha.jib \
--verbose \
--quiet \
--image-name ivarref/demo:latest \
--image-type docker \
-m main

Output on my machine:

+ echo '(ns main) (defn -main [& _] (println "Hello world"))'
+ echo '

I'm not sure what is to blame here. Tools.deps or Timbre.

Edit: Update to use local deps.edn file.

Thanks and kind regards.

Seems this is an issue with pack.alpha, so I will move it there.

Regards.
