To run the project via Maven:
mvn clean package exec:java
To create a 'fat' runnable jar file:
mvn clean package
To run the jar file created via package
java -jar target/{project-name}.jar [environment]
By default, the 'mvn package' goal will create a fat jar file including the configuration files in src/main/resources. These are loaded from the classpath at runtime. However, to override the values embedded in the jar file, simply create a new configuration file on the classpath for the desired environment. For example, './config/dev/environment.properties' and any settings in that file will get added to, or override settings embedded in the jar file.
