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.SimplifyMethodChainExample. 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.SimplifyMethodChainExample
displayName: Simplify a call chain example
recipeList:
  - org.openrewrite.java.SimplifyMethodChain:
      methodPatternChain: null
      newMethodName: null
Now that com.yourorg.SimplifyMethodChainExample has been defined activate it in your build file:
Gradle
Maven
build.gradle
plugins {
    id("org.openrewrite.rewrite") version("5.29.0")
}
​
rewrite {
    activeRecipe("com.yourorg.SimplifyMethodChainExample")
}
​
repositories {
    mavenCentral()
}
pom.xml
<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.openrewrite.maven</groupId>
        <artifactId>rewrite-maven-plugin</artifactId>
        <version>4.34.0</version>
        <configuration>
          <activeRecipes>
            <recipe>com.yourorg.SimplifyMethodChainExample</recipe>
          </activeRecipes>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>
Recipes can also be activated directly from the commandline by adding the argument -Drewrite.activeRecipes=com.yourorg.SimplifyMethodChainExample
