lombok.config

Create the lombok.config file with the custom configuration.

# tells Lombok that this is the root directory and that it shouldn't search parent directories for more configuration files
config.stopBubbling = true

# tells Lombok to add @lombok.Generated annotation to all generated methods
lombok.addLombokGeneratedAnnotation = true
