Você pode definir a lógica (código) que poderia ser executada antes da aplicação **inicializar**. Isso significa que esse código será executado **uma vez**, **antes** da aplicação **começar a receber requisições**.

Do mesmo modo, você pode definir a lógica (código) que será executada quando a aplicação estiver sendo **encerrada**. Nesse caso, este código será executado **uma vez**, **depois** de ter possivelmente tratado **várias requisições**.

== Step 1. Understanding Plugins
Plugins are the primary method to organize build logic and reuse build logic within a project.

Plugins are also used to distribute custom tasks as packaged code.
