deploying to heroku - clojure.main not found #5

Closed jennet closed 3 years ago

jennet commented 3 years ago

Back at the beginning of the course I found that my app was not deploying to heroku properly. I decided to leave it until the end of the course in case anything was amended along the way, but no joy.

The logs show:

The only thing I've done differently is that my project namespace is called cheffy-api rather than cheffy, but I still build the jar as cheffy.jar with :uberjar-name "cheffy.jar" in my project.clj

I can't see anything dubious in the log written when deploying to heroku

Any ideas?

jennet commented 3 years ago

After digging through Heroku clojure support and checking against the course files, it seems the Procfile was adjusted to 

web: java $JVM_OPTS -cp target/cheffy.jar clojure.main -m cheffy.server "resources/config.edn"

sometime around lesson 10

I've adjusted this for my project namespace and now the app starts OK.

I think you should probably mention this in the description of lesson 7 / Heroku deploy as I don't recall this ever being caught/explained in any of the lessons (though perhaps it was? I don't know)

Towards the end of the course I adopted the Heroku config 59 - Deploy

@jennet could we close this one? I added a note to lesson 7
