annotation class ComponentType

Declares a custom org.gradle.platform.base.ComponentSpec type. The following example demonstrates how to register a custom component type using a plugin with a ComponentType annotation. Furthermore the plugin creates an instance of SampleComponent named 'sampleComponent'.

    interface SampleComponent extends ComponentSpec {}
    class DefaultSampleComponent extends BaseComponentSpec implements SampleComponent {}

    apply plugin: MySamplePlugin

    class MySamplePlugin extends RuleSource {
        @ComponentType
        void register(TypeBuilder<SampleComponent> builder) {
            builder.defaultImplementation(DefaultSampleComponent)
        }

        @Mutate
        void createSampleLibraryComponents(ModelMap<SampleComponent> componentSpecs) {
            componentSpecs.create("sampleComponent")
        }
    }
