Options

Type
Name
Description
String
methodPattern
A method pattern that is used to find matching method invocations. The original method call may or may not be a static method invocation.
String
fullyQualifiedTargetTypeName
A fully-qualified class name of the type upon which the static method is defined.
String
returnType
Optional. Sometimes changing the target type also changes the return type. In the Guava example, changing from ImmutableSet#of(..) to Set#of(..) widens the return type from Guava's ImmutableSet to just java.util.Set.
Boolean
matchOverrides
Optional. When enabled, find methods that are overrides of the method pattern.
Boolean
matchUnknownTypes
Optional. When enabled, include method invocations which appear to match if full type information is missing. Using matchUnknownTypes can improve recipe resiliency for an AST with missing type information, but also increases the risk of false-positive matches on unrelated method invocations.

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.ChangeMethodTargetToStaticExample. 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.ChangeMethodTargetToStaticExample
displayName: Change method target to static example
recipeList:
- org.openrewrite.java.ChangeMethodTargetToStatic:
methodPattern: com.google.common.collect.ImmutableSet of(..)
fullyQualifiedTargetTypeName: java.util.Set
returnType: java.util.Set
matchOverrides: null
matchUnknownTypes: null
Now that com.yourorg.ChangeMethodTargetToStaticExample 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.ChangeMethodTargetToStaticExample")
}
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.ChangeMethodTargetToStaticExample</recipe>

</plugins>
</build>

Recipes can also be activated directly from the commandline by adding the argument -Drewrite.activeRecipes=com.yourorg.ChangeMethodTargetToStaticExample
