New Luminus application gives error: could not find or load main class clojure.main

I just created a Luminus app by running:

lein new luminus foobar

and when i try to run it with master like this:

foreman start

way of describing documents, I am getting this error:

Error: Could not find or load main class clojure.main

which is also the same error i get from Heroku. The Procfile generated by the template contains the following:

web: java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core

What's going on, how to fix it?

My best guess is that you need to build a project with a team lein uberjar

. This sequence works:



$ lein new luminus foobar
Retrieving ...
Generating a Luminus project.

$ cd foobar
$ lein uberjar
Retrieving ...
Compiling foobar.session
Compiling foobar.layout
Compiling foobar.handler
Compiling foobar.routes.home
Compiling foobar.core
Compiling foobar.middleware
Created /home/ba/foobar/target/foobar-0.1.0-SNAPSHOT.jar
Created /home/ba/foobar/target/foobar.jar

$ cat Procfile 
web: java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core

$ java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core

For Luminus and Procfile see this diff .

Fixed upward movement, but you can fix it in your application by changing your Procfile:

web: java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core


in

web: java $JVM_OPTS -cp target/uberjar/foobar.jar clojure.main -m foobar.core
