In order to launch the backend (via command line)...

1. Have a local database running (PostgreSQL preferred, but MySQL may also work)
2. Set up a file under backend/src/main/resources called application-local.properties
3. Configure the backend to connect to your local database:

# Example:
spring.datasource.url = jdbc:postgresql://localhost:5432/postgres
spring.datasource.username = postgres
spring.datasource.password = mysecretpassword

4. Move to the backend directory and compile using Maven:

cd backend
mvn -B clean package --file pom.xml

5. Run using the configured profile:

java -jar target/backend-0.0.1-SNAPSHOT.jar --spring.profiles.active=local
