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.ReplaceConstantExample. 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.ReplaceConstantExample
displayName: Replace constant with literal value example
recipeList:
  - org.openrewrite.java.ReplaceConstant:
      owningType: com.google.common.base.Charsets
      constantName: UTF_8
      literalValue: UTF_8

Now that com.yourorg.ReplaceConstantExample has been defined activate it in your build file:

Gradle

1. Add the following to your build.gradle file:

build.gradle

plugins {
    id("org.openrewrite.rewrite") version("6.11.2")
}

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

repositories {
    mavenCentral()
}

2. Run gradle rewriteRun to run the recipe.

Maven

1. Add the following to your pom.xml file:

pom.xml

<project>
  <build>
    <plugins>

        <artifactId>rewrite-maven-plugin</artifactId>

          </activeRecipes>
        </configuration>
      </plugin>
