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.ChangeLogLevelExample. 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.ChangeLogLevelExample
displayName: Change slf4j log level example
recipeList:
- org.openrewrite.java.logging.slf4j.ChangeLogLevel:
from: INFO
to: DEBUG
startsWith: LaunchDarkly
Now that com.yourorg.ChangeLogLevelExample has been defined activate it and take a dependency on org.openrewrite.recipe:rewrite-logging-frameworks:2.1.0 in your build file:
Gradle
Maven
