Options​

TypeNameDescriptionExample
StringmethodPatternA method pattern is used to find matching method invocations. For example, to find all method invocations in the Guava library, use the pattern: com.google.common..*#*(..).

The pattern format is <PACKAGE>#<METHOD_NAME>(<ARGS>).

..* includes all subpackages of com.google.common.
*(..) matches any method name with any number of arguments.

For more specific queries, like Guava's ImmutableMap, use com.google.common.collect.ImmutableMap#*(..) to narrow down the results.		com.yourorg.A foo(int, int)
intargumentIndexA zero-based index that indicates which argument will be removed from the method invocation.0

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.DeleteMethodArgumentExample. 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.DeleteMethodArgumentExample
displayName: Delete method argument example
recipeList:
  - org.openrewrite.java.DeleteMethodArgument:
      methodPattern: com.yourorg.A foo(int, int)
      argumentIndex: 0

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

  1. Add the following to your build.gradle file:
build.gradle
plugins {
    id("org.openrewrite.rewrite") version("7.6.1")
}

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

repositories {
    mavenCentral()
}
  1. Run gradle rewriteRun to run the recipe.
