Prefix string too short
Describe the bug
Attempting to build an uberjar with Selenium as a dependency raises the following exception:
clojure.lang.ExceptionInfo: Prefix string "9" too short: length must be at least 3
To Reproduce
build.boot:
(set-env!
:resource-paths #{"."}
:dependencies '[[org.clojure/clojure "1.10.1"]
[org.seleniumhq.selenium/selenium-support "3.141.59"]
[org.seleniumhq.selenium/selenium-remote-driver "3.141.59"]])
(task-options!
pom {:project 'selenium :version "0.1.0-SNAPSHOT"}
aot {:namespace #{'selenium}}
jar {:main 'selenium})
boot.properties:
BOOT_VERSION=2.8.3
BOOT_CLOJURE_VERSION=1.10.1
BOOT_CLOJURE_NAME=org.clojure/clojure
selenium.clj:
(ns selenium (:gen-class))
(defn -main [& args] ())
Run boot aot pom uber jar target
Expected behavior
Successful build and jar written to disk.
Actual behavior
Compiling 1/1 selenium...
Writing pom.xml and pom.properties...

I used a container to run the above i.e.
docker run -it --rm -v "$PWD":/usr/src/app -w /usr/src/app clojure:openjdk-15-boot-2.8.3-alpine boot aot pom uber jar target
Running boot -vv ... provides ALOT more information... but it mentions a "duplicate entry":

Can I work-around the problem with some :exclusions in the dependencies?
So the versions directory has something to do with multi-release jars, and in my case it's empty so I was able to work-around the issue by adding an extra exclude pattern to the uber task, i.e.
(task-options!
uber {:exclude #{#"(?i)^META-INF/INDEX.LIST$"
#"(?i)^META-INF/[^/]*\.(MF|SF|RSA|DSA)$"
#"(?i)^META-INF/versions/.$"}}
...)
But in general I suppose that the apply-mergers! will want to deal with one (and two) character directory names.
