Overview
A Gradle plugin is packaged code that uses the Gradle API to provide additional functionality and extend Gradle core. A Gradle plugin may introduce new tasks, new domain objects, conventions, project layouts and patterns for a specific problem domain. Plugins may even extend the core objects. Introducing their own conventions, plugins are "opinionated", encouraging the user to do things in a certain way. However, well written plugins must provide means to change the default conventions and make it work for non-standard projects.
Script Plugin
A script plugin is simply a file containing Gradle DSL code and possibly in-line Java and Groovy code. It can be thought as an "include file".
apply from: 'example.gradle'
Conventionally, the file has the ".gradle" extension, but this is not mandatory. The file can be loaded from the local filesystem, or from a remote location. Filesystem location is relative to the project directory. Remote locations are specified with HTTP URLs.
