So I'm in process of creating a small web app for myself using Java and Spring with Mongo. Right now I'm trying to deploy it to Heroku but without success so far.
I followed a list of commands to deploy my app from official Heroku website and also from YouTube tutorial and I'm facing an error that so far I couldn't solve.
I already had a project on GitHub and inserted these commands.
heroku login
git init
... I know i didn't have to since I have on git already
heroku git:remote -a tripadvisor-app-demo
and then
git add .
git commit -am "make it better"
git push heroku master
This is error stack trace:

If you need anything else just ask I will provide, also I hope I provide all necessary stuff and describe process of how I tried to deploy it.
