/**
* Declares a custom {@link org.gradle.platform.base.ComponentSpec} type.
*
* The following example demonstrates how to register a custom component type using a plugin with a
* {@link ComponentType} annotation.
* Furthermore the plugin creates an instance of SampleComponent named 'sampleComponent'.
*
* <pre autoTested='true'>
* interface SampleComponent extends ComponentSpec {}
* class DefaultSampleComponent extends BaseComponentSpec implements SampleComponent {}
*
* apply plugin: MySamplePlugin
*
* class MySamplePlugin extends RuleSource {
* {@literal @}ComponentType

* void createSampleLibraryComponents(ModelMap<SampleComponent> componentSpecs) {
