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
Moderne CLI
1.Add the following to your build.gradle file:
build.gradle
plugins {
    id("org.openrewrite.rewrite") version("6.5.6")
}
​
rewrite {
    activeRecipe("com.yourorg.ChangeLogLevelExample")
}
​
repositories {
    mavenCentral()
}
​
dependencies {
    rewrite("org.openrewrite.recipe:rewrite-logging-frameworks:2.1.0")
}
2.Run gradle rewriteRun to run the recipe.
1.Add the following to your pom.xml file:
pom.xml
<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.openrewrite.maven</groupId>
        <artifactId>rewrite-maven-plugin</artifactId>
        <version>5.13.0</version>
        <configuration>
          <activeRecipes>
            <recipe>com.yourorg.ChangeLogLevelExample</recipe>
          </activeRecipes>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>org.openrewrite.recipe</groupId>
            <artifactId>rewrite-logging-frameworks</artifactId>
            <version>2.1.0</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>
2.Run mvn rewrite:run to run the recipe.
You will need to have configured the Moderne CLI on your machine before you can run the following command.
shell
mod run . --recipe ChangeLogLevel
