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.ResultOfMethodCallIgnoredExample. 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.ResultOfMethodCallIgnoredExample
displayName: Result of method call ignored example
recipeList:
- org.openrewrite.java.search.ResultOfMethodCallIgnored:
methodPattern: java.io.File mkdir*()
matchOverrides: null
