Hay una forma alternativa de definir esta lógica para ser ejecutada durante el *startup* y durante el *shutdown*.

Puedes definir manejadores de eventos (funciones) que necesitan ser ejecutadas antes de que la aplicación se inicie, o cuando la aplicación se está cerrando.

Estas funciones pueden ser declaradas con `async def` o `def` normal.

### Evento `startup` { #startup-event }

However, this would limit the ability of the Gradle ecosystem plugin authors to take advantage of new Java features and improvements.

One example is when one of the most popular plugins started requiring Java 17 because the underlying framework behind the plugin began requiring 17, and code from the framework was used in the plugin itself.
What would have happened if Gradle was limited to _only Java 11_ at the time?
