Deploying a Spring boot app to Heroku

Question

I've been recently trying to deploy an app to Heroku, but it has been proven to be a nightmare to do so. I've got a little web app that works just fine when run locally on my computer, but when run on Heroku, it complaints about a number of errors and I dont have an idea why. I've spent good 10 hours trying to figure out whats going on, but I'm no wiser :/

This is the error I'm getting on Heroku:
