All Implemented Interfaces:
io.micronaut.core.naming.Described, io.micronaut.core.naming.Named, io.micronaut.core.order.Ordered, DefaultFeature, Feature, LanguageFeature, OpenRewriteFeature
@Requires(property="micronaut.starter.feature.kotlin.enabled", value="true", defaultValue="true") @Singleton public class Kotlin extends Object implements LanguageFeature, OpenRewriteFeature
Represents the Kotlin language feature for the project generator.

This class manages Kotlin application features, processes feature selection, applies Kotlin-specific configurations such as setting the Kotlin version,

    • getName

      @NonNull public @NonNull String getName()
      Description copied from interface: Feature
      The name of the feature. It must be unique.
      Specified by:
      getName in interface Feature
      Specified by:
      getName in interface io.micronaut.core.naming.Named
      Returns:
      the name of the feature

    • processSelectedFeatures

      public void processSelectedFeatures(FeatureContext featureContext)
      Description copied from interface: Feature
      If this method is called for a given feature then that feature was explicitly selected or was included by default as a result of DefaultFeature.shouldApply(io.micronaut.starter.options.Options, java.util.Set). This method can be implemented to allow features to modify the list of features that will apply to the project. The methods FeatureContext.addFeature(Feature) and FeatureContext.exclude(FeaturePredicate) are the primary ways to add and remove features from the context. FeatureContext.isPresent(Class) can be used to determine the existence of other features in order to make decisions.
      Specified by:
      processSelectedFeatures in interface Feature
      Parameters:
      featureContext - The feature context

    • processSelectedFeatures

      protected void processSelectedFeatures(FeatureContext featureContext, Predicate<Feature> filter)
      Processes selected features by adding ApplicationFeature based on the application type if none is explicitly present.
      Parameters:
      featureContext - The context containing selected features.
      filter - Predicate to filter applicable features.

    • apply

      public void apply(GeneratorContext generatorContext)
      Description copied from interface: Feature
      If this method is called for a given feature that means the feature was explicitly selected, included by default as a result of DefaultFeature.shouldApply(io.micronaut.starter.options.Options, java.util.Set), or added explicitly by another feature through FeatureContext.addFeature(Feature). At this point the feature list is set and cannot change.
      Specified by:
      apply in interface Feature
      Specified by:
      apply in interface OpenRewriteFeature
      Parameters:
      generatorContext - THe generator context

    • addKotlinVersionProperty

      protected void addKotlinVersionProperty(GeneratorContext generatorContext, ModuleContext module)
      Adds the Kotlin version property to the build based on the resolved Kotlin BOM coordinate.
      Parameters:
      generatorContext - The context for project generation.
      module - The module to which the property should be added.

    • getRecipes

      public List<String> getRecipes(GeneratorContext generatorContext)
      Specified by:
      getRecipes in interface OpenRewriteFeature

    • isKotlin

      public boolean isKotlin()
      Specified by:
      isKotlin in interface LanguageFeature

    • shouldApply

      public boolean shouldApply(Options options, Set<Feature> selectedFeatures)
      Description copied from interface: DefaultFeature
      Determines if the feature should be applied to the project. Default features do not need to be concerned if the feature was already selected and therefore is already in the list of selected features. The addition to the set is based on the identity of the feature instance and all features are singletons.
      Specified by:
      shouldApply in interface DefaultFeature
      Parameters:
      options - The options
      selectedFeatures - The features manually selected by the user
      Returns:
      True if the feature should apply
