Usage

This recipe has required configuration parameters. Recipes with required configuration parameters cannot be activated directly (unless you are running them via the Moderne CLI). 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.ReplaceConstantWithAnotherConstantExample. 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.ReplaceConstantWithAnotherConstantExample
displayName: Replace constant with another constant example
recipeList:
  - org.openrewrite.java.ReplaceConstantWithAnotherConstant:
      existingFullyQualifiedConstantName: org.springframework.http.MediaType.APPLICATION_JSON_VALUE
      fullyQualifiedConstantName: org.springframework.http.MediaType.APPLICATION_JSON_VALUE

Now that com.yourorg.ReplaceConstantWithAnotherConstantExample 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("7.6.2")
}

rewrite {
    activeRecipe("com.yourorg.ReplaceConstantWithAnotherConstantExample")
    setExportDatatables(true)
}

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>
      <plugin>
        <groupId>org.openrewrite.maven</groupId>
        <artifactId>rewrite-maven-plugin</artifactId>
        <version>6.9.0</version>
        <configuration>
          <exportDatatables>true</exportDatatables>
          <activeRecipes>
            <recipe>com.yourorg.ReplaceConstantWithAnotherConstantExample</recipe>
          </activeRecipes>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

2. Run mvn rewrite:run to run the recipe.
