​Thank you. I thought so, but it is better to be sure.

There's no need for `:aot [quotes.core]` if you're using `:aot :all` in your 
uberjar profile. The only other reason you'd want it is to AOT that namespace 
outside of the uberjar profile. That's up to you, but typically not a concern.

​That is why it is smart to communicate small non essential changes: people
can set you on the right track. :-)

I put that back. I now removed the ‘:aot [quotes.core]’, or should I keep
that also?

When I first got the error I found two different pieces of advice. One for
both changes. When those did not work I asked here.


I should pick up Clojure again. I only did one little project (long ago) to
try it out. But that is no way to learn a language. Sadly there is no real
use here for it. :'-(

For the best performance, you likely want AOT (ahead-of-time) compilation. In 
general, I'd recommend keeping that uberjar profile with `{:aot :all}`.

​That was what was needed. Thanks.

And I could remove the added:
:profiles {
:uberjar {:aot :all}
  }

The warning which lein provided is trying to tell you exactly what you need to 
do. In the `ns` form of your quotes.core namespace, you should add a 
(:gen-class). Example:

```clojure
(ns quotes.core
  (:gen-class))
```

Trying to make an uberjar

2017-03-03 Thread Cecil Westerhof 
Until now I can run my project without a problem with:
lein trampoline run &

But I was told that I should use an uberjar.

My project.clj was:
(defproject quotes "0.0.1"
  :description "Initial quotes application"
  :url "http://example.com/FIXME;
  :dependencies [[org.clojure/clojure"1.8.0"]
 [clj-time   "0.12.0"]
 [com.h2database/h2  "1.3.176"]
 [instaparse "1.4.2"]
 [org.clojure/math.numeric-tower "0.0.4"]
 [seesaw "1.4.5"]
 [yesql  "0.5.3"]]
  :main quotes.core
  :jvm-opts ["-Xmx320m"]
)

That did not work. So I changed it to:
(defproject quotes "0.0.1"
  :description "Initial quotes application"
  :url "http://example.com/FIXME;
  :dependencies [[org.clojure/clojure"1.8.0"]
 [clj-time   "0.12.0"]
 [com.h2database/h2  "1.3.176"]
 [instaparse "1.4.2"]
 [org.clojure/math.numeric-tower "0.0.4"]
 [seesaw "1.4.5"]
 [yesql  "0.5.3"]]
  :main quotes.core
  :aot [quotes.core]
  :profiles {
:uberjar {:aot :all}
  }
  :jvm-opts ["-Xmx320m"]
)

But when running:
lein uberjar
I still get:
This code is executed when starting Clojure.
Compiling quotes.core
Warning: The Main-Class specified does not exist within the jar. It may not
be executable as expected. A gen-class directive may be missing in the
namespace which contains the main method, or the namespace has not been
AOT-compiled.
Created /home/cecil/Clojure/Quotes/target/quotes-0.0.1.jar
Created /home/cecil/Clojure/Quotes/target/quotes-0.0.1-standalone.jar

What do I need to change to make an uberjar. (Jars are generated, but
cannot be used.)
