Hi Varen Bath!
Have you built the project with mvn clean install ? You have to install maven 3 first and then run the above command at the project root directory.
I haven’t improved the project to work as a distribution. Therefore, you have to open the project in an IDE (preferred IntelliJ IDEA) and open this project as a maven project and then run it. You may need to set the working directory to the resources folder under run configurations.
