You could run this project simply with Clojure, and it should print HOLA:
$ clojure -M -m my.lib
HOLA
$
That's fine. Now, you can build a jar with this task:
$ clojure -T:build uber
$
And the jar will be located at target as target/lib1-0.1-standalone.jar
That's fine. Now, the problem is that that jar file doesn't print HOLA with the following command
$ java -jar target/lib1-0.1-standalone.jar
$
What am I doing wrong?
Note: I followed this official document for writing my build.clj file: https://clojure.org/guides/tools_build#_compiled_uberjar_application_build
