How to include dependencies into JAR file (Maven)

Question

I've tried every solution I came across on here relating to this topic, but I am still not able to find a solution.

When running my project in Eclipse (Spring Boot + Maven),everything runs smooth. I am able to see some JSON data from an API call. My goal is to deploy this project on CloudFoundry, but I constantly get ClassNotFound error (Java). Below is my POM file.

I've tried exporting as a Runnable JAR and running that jar via command line, but I also get the NoClassFound error.
