# Class JavaPlugin

java.lang.Object
org.gradle.api.plugins.JavaPlugin

All Implemented Interfaces:
  `Plugin<Project>`

public abstract class JavaPlugin extends Object implements Plugin<Project>

A `Plugin` which compiles and tests Java source, and assembles it into a JAR file.

This plugin creates a built-in `test suite` named `test` that represents the `Test` task for Java projects.
