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.ParameterizedLoggingExample. Here's how you can define and customize such a recipe within your rewrite.yml:

{% code title="rewrite.yml" %}

---
type: specs.openrewrite.org/v1beta/recipe
name: com.yourorg.ParameterizedLoggingExample
displayName: Parameterize logging statements example
recipeList:
  - org.openrewrite.java.logging.ParameterizedLogging:
      methodPattern: org.slf4j.Logger info(..)
      removeToString: null

{% endcode %}

Now that com.yourorg.ParameterizedLoggingExample has been defined activate it and take a dependency on org.openrewrite.recipe:rewrite-logging-frameworks:2.0.1 in your build file: {% tabs %} {% tab title="Gradle" %} {% code title="build.gradle" %}

plugins {
    id("org.openrewrite.rewrite") version("6.1.4")
}

rewrite {
    activeRecipe("com.yourorg.ParameterizedLoggingExample")
}

repositories {
    mavenCentral()
}

dependencies {
    rewrite("org.openrewrite.recipe:rewrite-logging-frameworks:2.0.1")
}

{% endcode %} {% endtab %} {% tab title="Maven" %} {% code title="pom.xml" %}

          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>

{% endcode %} {% endtab %} {% endtabs %}
