ExtensionAware

Represents an object that is able to accept DSL extensions. A DSL extension is basically a custom namespace in the DSL.

To add an extension to this object, you call ExtensionContainer.add() on this object's ExtensionContainer, passing the extension object. The extension becomes a dynamic property of this target object:

extensions.add('custom', new MyPojo())

// Extension is available as a property
custom.someProperty = 'value'

// And as a script block
custom {
    someProperty = 'value'
}

class MyPojo {
    String someProperty
}

Extensions can also be added using a dynamic property accessor on the extension container: project.extensions.myExtension = myPojo is the same as project.extensions.add('myExtension', myPojo).

Many Gradle types implement this interface, either statically or dynamically at runtime.
