Heroku - Java Maven project depoly - getting application error after complete git push heroku master

Question

I've made a simple Java web app using Maven and I'm trying to deploy it. At first, I've got an error:

error: src refspec master does not match any.
error: failed to push some refs to 'git@heroku.com: etc ...'

however, I found a solution to it here: I want make push and get error: src refspec master does not match any

After a while I get the following information in my terminal:

remote:        [INFO] BUILD SUCCESS

But when I try heroku open or just go the URL there is just info: Application Error.

Here are my heroku logs:

It is my 1st time ever deploying any Java project to the web and I get confused, I don't really understand what is wrong and how to fix it.

After adding Procfile: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war

I've got error again and here are my logs:

In your build log it says:

remote:        Procfile declares types -> (none)

This means Heroku won't start any processes, which is why you get the "No web processes running" error.

What does your Procfile look like? It is probably empty. You'll need something like this:

web: java -jar target/myapp.jar

Replace the java command with the appropriate java command to start your app.

Hello! I'll definitely try your solution as and let know if that worked :) I was doing it according to this guidance: https://devcenter.heroku.com/articles/procfile#developing-locally And there was info: Deploying to Heroku A Procfile is not necessary to deploy apps written in most languages supported by Heroku. The platform automatically detects the language, and creates a default web process type to boot the application server. So I don't even add Procfile to my project. – Luke_Nuke Oct 03 '18 at 14:16
I've added following in the Procfile: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war – Luke_Nuke Oct 03 '18 at 20:40
I've added following in the Procfile: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war Saved it as Procfile with no extensions in the main folder of the project then commit and push again, however, I got extended log I've added it to the original post. – Luke_Nuke Oct 03 '18 at 20:53
did you see `Procfile declares types -> web` in your build output? try `heroku ps:scale web=1` – codefinger Oct 03 '18 at 21:05
It returns me that: $ heroku ps:scale web=1 Scaling dynos... ! ! Couldn't find that process type. So my Procfile is still wrong? – Luke_Nuke Oct 03 '18 at 21:11
