Usage

This recipe has required configuration parameters. Recipes with required configuration parameters cannot be activated directly. To activate this recipe you must create a new recipe which fills in the required parameters. In your rewrite.yml create a new recipe with a unique name. For example: com.yourorg.FindImplementationsExample. Here's how you can define and customize such a recipe within your rewrite.yml:
rewrite.yml
---
type: specs.openrewrite.org/v1beta/recipe
name: com.yourorg.FindImplementationsExample
displayName: Find class declarations implementing an interface example
recipeList:
- org.openrewrite.java.search.FindImplementations:
interfaceFullyQualifiedName: org.openrewrite.Recipe
matchInherited: null
Now that com.yourorg.FindImplementationsExample has been defined activate it in your build file:
Gradle
Maven
Moderne CLI

}
repositories {
mavenCentral()
}
