Type	Name	Description	Example
`String`	methodPattern	A pattern to match method invocations for removal. A 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.	`java.lang.StringBuilder append(java.lang.String)`

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.RemoveMethodInvocationsExample. 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.RemoveMethodInvocationsExample
displayName: Remove method invocations example
recipeList:
  - org.openrewrite.java.RemoveMethodInvocations:
      methodPattern: java.lang.StringBuilder append(java.lang.String)

This recipe has no required configuration parameters and comes from a rewrite core library. It can be activated directly without adding any dependencies.

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

Gradle
Maven POM
Moderne CLI

Add the following to your build.gradle file:

build.gradle

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

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

repositories {
    mavenCentral()
}

Run gradle rewriteRun to run the recipe.
