Gradle Plugins TODEPLETE

Overview

A Gradle plugin is packaged code that uses the Gradle API to provide additional functionality and extend Gradle core. A Gradle plugin applies some configuration to a target object, usually a Project. The 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.

Plugin API

org.gradle.api.Plugin<T>

Script Plugin

https://docs.gradle.org/current/userguide/plugins.html#sec:script_plugins

A script plugin is simply a file containing Gradle DSL code and possibly in-line Java and Groovy code. It can be thought as just another build script that can be imported into a build script.

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.

Binary Plugin

A binary plugin is a class implementing org.gradle.api.Plugin and ancillary classes.

Using a Plugin

Plugins can be applied in two ways:

apply() method

apply plugin: 'java'

plugins script block

plugins {
}

Plugin Extension

A plugin is a typical use case for an extension.

Standard Plugins

A standard plugin ships with the Gradle runtime.

Plugin Libraries

External Plugins

Writing Custom Plugins

Custom Binary Plugins
