This includes software that is implemented using Java, Kotlin or some other JVM language.

This platform provides specific support for Java, Groovy and Scala, and includes the foojay toolchain plugin. 

#### Extensibility platform

This is a platform that builds on the core, software and JVM platforms to add support for extending Gradle by implementing and applying plugins.

Algunos casos de uso incluyen:

### Tags com Enums { #tags-with-enums }

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a **mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.
