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.ChangeDependencyClassifierExample. 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.ChangeDependencyClassifierExample
displayName: Change Maven dependency classifier example
recipeList:
  - org.openrewrite.maven.ChangeDependencyClassifier:
      groupId: com.google.guava
      artifactId: guava
      newClassifier: jar
      changeManagedDependency: true

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

  1. Add the following to your pom.xml file:
pom.xml
<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.openrewrite.maven</groupId>
        <artifactId>rewrite-maven-plugin</artifactId>
        <version>6.10.0</version>
        <configuration>
          <exportDatatables>true</exportDatatables>
          <activeRecipes>
            <recipe>com.yourorg.ChangeDependencyClassifierExample</recipe>
          </activeRecipes>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>
  1. Run mvn rewrite:run to run the recipe.
