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.UseStaticImportExample. 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.UseStaticImportExample
displayName: Use static import example
recipeList:
- org.openrewrite.java.UseStaticImport:
methodPattern: java.util.Collections emptyList()
Now that com.yourorg.UseStaticImportExample has been defined activate it in your build file:
Gradle
Maven
build.gradle
plugins {
id("org.openrewrite.rewrite") version("5.34.0")
}
rewrite {
activeRecipe("com.yourorg.UseStaticImportExample")
}
repositories {
mavenCentral()
}
pom.xml

<configuration>
<activeRecipes>
<recipe>com.yourorg.UseStaticImportExample</recipe>
