So what I'm trying to do is to deploy my Spring Boot App to Heroku (using Git and Heroku CLI).
But every time I push my repo to Heroku, these errors appear after I used "$git push heroku master" in my terminal.
remote: [ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.6.2:repackage (repackage) on project UserEditor: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.6.2:repackage failed: Unable to find main class -> [Help 1]
