### 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.

This platform includes the plugin publishing plugin and the plugin portal.

### Native platform

This is a platform that builds on the core and software platforms to add support for developing native software.

A dependency on a platform is created using the `platform` keyword:
