# extra

val ExtensionAware.extra: ExtraPropertiesExtension(source)

The extra properties extension in this object's extension container.

For a org.gradle.api.Project, this accesses only that project's extra properties. Values set explicitly on the extension take precedence over Gradle properties with the same name when those properties are not mapped directly to a `Project` property. This does not perform the broader lookup used by org.gradle.api.Project.findProperty.
