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.DoesNotUseTypeExample
.
Here's how you can define and customize such a recipe within your rewrite.yml:
---
type: specs.openrewrite.org/v1beta/recipe
name: com.yourorg.DoesNotUseTypeExample
displayName: Check whether a type is **not** in use example
recipeList:
- org.openrewrite.java.search.DoesNotUseType:
fullyQualifiedTypeName: java.util.List
Now that com.yourorg.DoesNotUseTypeExample
has been defined, activate it in your build file:
- Gradle
- Maven
- Moderne CLI
- Add the following to your
build.gradle
file:
plugins {
id("org.openrewrite.rewrite") version("6.25.0")
}
rewrite {
activeRecipe("com.yourorg.DoesNotUseTypeExample")
exportDatatables = true
}
repositories {
mavenCentral()
}
- Run
gradle rewriteRun
to run the recipe.
- Add the following to your
pom.xml
file:
<project>
<build>
<plugins>
<plugin>
<groupId>org.openrewrite.maven</groupId>
<artifactId>rewrite-maven-plugin</artifactId>
<version>5.42.0</version>
<configuration>
<exportDatatables>true</exportDatatables>
<activeRecipes>
<recipe>com.yourorg.DoesNotUseTypeExample</recipe>
</activeRecipes>
</configuration>
</plugin>
</plugins>
</build>
</project>
- Run
mvn rewrite:run
to run the recipe.
You will need to have configured the Moderne CLI on your machine before you can run the following command.
mod run . --recipe DoesNotUseTypeExample
