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.UpgradeJavaVersionExample. 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.UpgradeJavaVersionExample
displayName: Upgrade Java version example
recipeList:
  - org.openrewrite.java.migrate.UpgradeJavaVersion:
      version: 11
Now that com.yourorg.UpgradeJavaVersionExample has been defined activate it and take a dependency on org.openrewrite.recipe:rewrite-migrate-java:2.3.0 in your build file:
Gradle
Maven
Moderne CLI
1.Add the following to your build.gradle file:
build.gradle
plugins {
    id("org.openrewrite.rewrite") version("6.5.6")
}
​
rewrite {
    activeRecipe("com.yourorg.UpgradeJavaVersionExample")
}
​
repositories {
    mavenCentral()
}
​
dependencies {
    rewrite("org.openrewrite.recipe:rewrite-migrate-java:2.3.0")
}
2.Run gradle rewriteRun to run the recipe.
1.Add the following to your pom.xml file:
pom.xml

        <dependencies>
          <dependency>

            <artifactId>rewrite-migrate-java</artifactId>
            <version>2.3.0</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
