Package with Clojure tools.buildλ︎
The 
Clojure.org tools.build project is used to build jar files to deploy libraries and uberjar files to run deployed projects (e.g. in Docker containers or directly on an Operating System with Java JVM installed).
Clojure tools.build is a library to define build related tasks using Clojure code.
Practicalli Project Templates includes tools.build configuration
Clojure projects created with Practicalli Project Templates include a build.clj configuration to build an uberjar of the project.
The make build-jar runs the clojure -T:build jar command to build an uberjar.
Java ARchive - jar file
A .jar file is a zip archive of the project containing all the files for running a Clojure project. The archive should contain metatdata files such as Manifest and pom.xml and can contain Clojure sources or compiled class files from the project (or both).
An ubjerjar is .jar file that also contains all the project dependencies including Clojure. The uberjar is a self-contained file that can be easily deployed and requires only a Java run-time (Java Virtual Machine), using the java -jar project-uberjar.jar command, with the option to pass arguments to the Uberjar also.
Practicalli Project templates include a build.clj configuration with jar and uberjar tasks.
Create a runnable Clojure archive

tools.build provides an API for pragmatically defining tasks to build Clojure projects.
Create a build.clj configuration with tasks for building a library jar or runable uberjar.
