Options

Type	Name	Description	Example
String	methodPattern	A method pattern that is used to find matching method invocations.	com.yourorg.A foo(String, Integer, Integer)
String[]	newParameterNames	An array of parameter names that indicates the new order in which those arguments should be arranged.	[foo, bar, baz]
String[]	oldParameterNames	Optional. If the original method signature is not type-attributed, this is an optional list that indicates the original order in which the arguments were arranged.	[baz, bar, foo]
Boolean	ignoreDefinition	Optional. When set to true the definition of the old type will be left untouched. This is useful when you're replacing usage of a class but don't want to rename it.
Boolean	matchOverrides	Optional. When enabled, find methods that are overrides of the method pattern.

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.ReorderMethodArgumentsExample. 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.ReorderMethodArgumentsExample
displayName: Reorder method arguments example
recipeList:
  - org.openrewrite.java.ReorderMethodArguments:
      methodPattern: com.yourorg.A foo(String, Integer, Integer)
      newParameterNames: [foo, bar, baz]
      oldParameterNames: [baz, bar, foo]

Now that com.yourorg.ReorderMethodArgumentsExample 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("6.12.0")
}

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

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>5.29.0</version>
        <configuration>
          <activeRecipes>
            <recipe>com.yourorg.ReorderMethodArgumentsExample</recipe>
          </activeRecipes>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

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