how to package and start your clojure application?

Like many JVM languages, packaging and starting a JVM application can be done in a multitude of ways. What are some solid ways of packaging large clojure projects having lots of both clojure and Java dependencies, for deploying and starting them in production-like environments?

With leiningen, you can simply package through:

lein uberjar

This will package all the dependencies and your code into one jar that you can then run via: 

java -jar uberjar.jar

For that to work however, you have to specify a :main namespace in your project.clj, which will trigger AOT, the latter considered undesirable for other causes such as for being able to cleanly use clojure.tools.namespace over your project. So to avoid AOT, you can skip specifying a :main namespace in your project.clj, and simply run with the slightly more verbose command:

java -jar uberjar.jar clojure.main -m your.main.namespace
