The Clojure install script (https://download.clojure.org/install/linux-install-1.10.1.708.sh, the one used in clojure-1.10.1-10) has the line:

install -Dm644 clojure-tools/exec.jar "$clojure_lib_dir/libexec/exec.jar"

However, clojure-1.10.1-10 doesn't include that file:

$ pacman -Q clojure
clojure 1.10.1-10
$ pacman -Ql clojure
clojure /etc/
clojure /etc/profile.d/
clojure /etc/profile.d/clojure.sh
clojure /usr/
clojure /usr/bin/
clojure /usr/bin/clj
clojure /usr/bin/clojure
clojure /usr/share/
clojure /usr/share/clojure/
clojure /usr/share/clojure/deps.edn
clojure /usr/share/clojure/example-deps.edn
clojure /usr/share/clojure/libexec/
clojure /usr/share/clojure/libexec/clojure-tools-1.10.1.708.jar
clojure /usr/share/man/
clojure /usr/share/man/man1/
clojure /usr/share/man/man1/clj.1.gz
clojure /usr/share/man/man1/clojure.1.gz

This breaks a recent Clojure feature that lets you execute a given function from the command line: https://clojure.org/reference/deps_and_cli#_executing_a_function

Expected behavior:

$ clojure -X clojure.core/prn :foo "bar"
{:foo bar}

Actual behavior:

$ clojure -X clojure.core/prn :foo "bar"
Execution error (FileNotFoundException) at clojure.main/main (main.java:40).
Could not locate clojure/run/exec__init.class, clojure/run/exec.clj or clojure/run/exec.cljc on classpath.
