Code standards

Your code is automatically formatted according to the Import and Code Style conventions during every Maven build. CI checks enforce those conventions too, so be sure to build your project with maven before creating your PR:

mvn clean install

For information about how to set up code style checks, see IDE Setup Instructions.
