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.UpgradeAssistantAnalyzeExample. 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.UpgradeAssistantAnalyzeExample
displayName: Analyze a .NET project using upgrade-assistant example
recipeList:
  - org.openrewrite.dotnet.UpgradeAssistantAnalyze:
      targetFramework: net9.0
      privacyMode: Restricted

Now that com.yourorg.UpgradeAssistantAnalyzeExample has been defined, activate it and take a dependency on org.openrewrite.recipe:rewrite-dotnet:0.2.0 in your build file:

Gradle

1. Add the following to your build.gradle file:

build.gradle

plugins {
    id("org.openrewrite.rewrite") version("6.24.0")
}

rewrite {
    activeRecipe("com.yourorg.UpgradeAssistantAnalyzeExample")
    exportDatatables = true
}

repositories {
    mavenCentral()
}

dependencies {
    rewrite("org.openrewrite.recipe:rewrite-dotnet:0.2.0")
}

2. Run gradle rewriteRun to run the recipe.

Maven

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>5.41.0</version>
        <configuration>
          <exportDatatables>true</exportDatatables>
          <activeRecipes>
            <recipe>com.yourorg.UpgradeAssistantAnalyzeExample</recipe>
          </activeRecipes>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>org.openrewrite.recipe</groupId>
            <artifactId>rewrite-dotnet</artifactId>
            <version>0.2.0</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>

2. Run mvn rewrite:run to run the recipe.
