Abstract method error when pushing jhipster micro service to cloud foundry - maven

Question

I am trying to push my jhipster microservice to Cloud foundry. The micro service works correctly locally when I package it up for production, but it fails on the push to Cloud Foundry.
Background: I have a jar from the EGADS library, but I changed some of the source code for the functionality that I wanted. So I am using that as a 3rd party jar file in my micro service.
The logs from cloud foundry are as follows:

Could the problem also stem from the pom file from the 3rd party jar I am using? I am just trying to figure out where the problems comes from.
I have looked at How to set up Spring Boot and log4j2 properly?, Log4J 2 version not working with RabbitMQ & Spring Boot, spring-boot + cloud log4j version compatibity issue when using SerialisedLayout socket appender, and more but I haven yet to find anything that solves my issue.
