In order to build the project edit application.properties file to use your database.
Create (if you don't have) database with 1 collection: sequences.
Then insert 1 document(_id: "events", sequence: 0) in sequences.
In order to build the project itself run:
./gradlew build
./gradlew build
./gradlew bootRun
Or you can simply run:
java -jar ./build/libs/events-geo-positioning-1.1.2-SNAPSHOT.jar
