| # Rewrite recipe starter | ||
| # Rewrite Docker | ||
|
|
||
| This repository serves as a template for building your own recipe JARs and publishing them to a repository where they can be applied on [app.moderne.io](https://app.moderne.io) against all the public OSS code that is included there. | ||
|
|
||
| We've provided a sample recipe (NoGuavaListsNewArray) and a sample test class. Both of these exist as placeholders, and they should be replaced by whatever recipe you are interested in writing. | ||
|
|
||
| To begin, fork this repository and customize it by: | ||
|
|
||
| 1. Changing the root project name in `settings.gradle.kts`. | ||
| 2. Changing the `group` in `build.gradle.kts`. | ||
| 3. Changing the package structure from `com.yourorg` to whatever you want. | ||
|
|
||
| ## Getting started | ||
|
|
||
| Familiarize yourself with the [OpenRewrite documentation](https://docs.openrewrite.org/), in particular the [concepts & explanations](https://docs.openrewrite.org/concepts-explanations) op topics like the [lossless semantic trees](https://docs.openrewrite.org/concepts-explanations/lossless-semantic-trees), [recipes](https://docs.openrewrite.org/concepts-explanations/recipes) and [visitors](https://docs.openrewrite.org/concepts-explanations/visitors). | ||
|
|
||
| You might be interested to watch some of the [videos available on OpenRewrite and Moderne](https://www.youtube.com/@moderne-auto-remediation). | ||
|
|
||
| Once you want to dive into the code there is a [comprehensive getting started guide](https://docs.openrewrite.org/authoring-recipes/recipe-development-environment) | ||
| available in the OpenRewrite docs that provides more details than the below README. | ||
|
|
||
| ## Reference recipes | ||
|
|
||
| * [META-INF/rewrite/stringutils.yml](./src/main/resources/META-INF/rewrite/stringutils.yml) - A declarative YAML recipe that replaces usages of `org.springframework.util.StringUtils` with `org.apache.commons.lang3.StringUtils`. | ||
| * [UseApacheStringUtilsTest](./src/test/java/com/yourorg/UseApacheStringUtilsTest.java) - A test class for the `com.yourorg.UseApacheStringUtils` recipe. | ||
| * [NoGuavaListsNewArrayList.java](./src/main/java/com/yourorg/NoGuavaListsNewArrayList.java) - An imperative Java recipe that replaces usages of `com.google.common.collect.Lists` with `new ArrayList<>()`. | ||

| * [AppendToReleaseNotesTest](./src/test/java/com/yourorg/AppendToReleaseNotesTest.java) - A test class for the `AppendToReleaseNotes` recipe. | ||
| * [ClassHierarchy](./src/main/java/com/yourorg/ClassHierarchy.java) - A recipe that demonstrates how to produce a data table on the class hierarchy of a project. | ||
| * [ClassHierarchyTest](./src/test/java/com/yourorg/ClassHierarchyTest.java) - A test class for the `ClassHierarchy` recipe. | ||
| * [UpdateConcoursePipeline](./src/main/java/com/yourorg/UpdateConcoursePipeline.java) - A recipe that demonstrates how to update a Concourse pipeline, as an example of operating on Yaml files. | ||
| * [UpdateConcoursePipelineTest](./src/test/java/com/yourorg/UpdateConcoursePipelineTest.java) - A test class for the `UpdateConcoursePipeline` recipe. | ||
|
|
||
| ## Local Publishing for Testing | ||
|
|
||
| Before you publish your recipe module to an artifact repository, you may want to try it out locally. | ||
| To do this on the command line, using `gradle`, run: | ||
|
|
||
| ```bash | ||
| ./gradlew publishToMavenLocal | ||
| # or ./gradlew pTML | ||
| # or mvn install | ||
| ``` | ||
|
|
||
| To publish using maven, run: | ||
|
|
||
| ```bash | ||
| ./mvnw install | ||
| ``` | ||
|
|
||
| This will publish to your local maven repository, typically under `~/.m2/repository`. | ||
|
|
||
| Replace the groupId, artifactId, recipe name, and version in the below snippets with the ones that correspond to your recipe. | ||
|
|
||
| In the pom.xml of a different project you wish to test your recipe out in, make your recipe module a plugin dependency of rewrite-maven-plugin: | ||
|
|
||
| ```xml | ||
| <project> | ||
| <build> | ||
| <plugins> | ||
| <plugin> | ||
| <groupId>org.openrewrite.maven</groupId> | ||
| <artifactId>rewrite-maven-plugin</artifactId> | ||
| <version>RELEASE</version> | ||
| <configuration> | ||
| <activeRecipes> | ||
| <recipe>com.yourorg.NoGuavaListsNewArrayList</recipe> | ||
| </activeRecipes> | ||
| </configuration> | ||
| <dependencies> | ||
| <dependency> | ||
| <groupId>com.yourorg</groupId> | ||
| <artifactId>rewrite-recipe-starter</artifactId> | ||
| <version>0.1.0-SNAPSHOT</version> | ||
| </dependency> | ||
| </dependencies> | ||
| </plugin> | ||
| </plugins> | ||
| </build> | ||
| </project> | ||
| ``` | ||
|
|
||
| Unlike Maven, Gradle must be explicitly configured to resolve dependencies from Maven local. | ||
| The root project of your Gradle build, make your recipe module a dependency of the `rewrite` configuration: | ||
|
|
||
| ```groovy | ||
| plugins { | ||
| id("java") | ||
| id("org.openrewrite.rewrite") version("latest.release") | ||
| } | ||
| repositories { | ||
| mavenLocal() | ||
| mavenCentral() | ||
| } | ||
| dependencies { | ||
| rewrite("com.yourorg:rewrite-recipe-starter:latest.integration") | ||
| } | ||
| rewrite { | ||
| activeRecipe("com.yourorg.NoGuavaListsNewArrayList") | ||
| } | ||
| ``` | ||
|
|
||
| Now you can run `mvn rewrite:run` or `gradlew rewriteRun` to run your recipe. | ||
|
|
||
| ## Publishing to Artifact Repositories | ||
|
|
||
| This project is configured to publish to Moderne's open artifact repository (via the `publishing` task at the bottom of | ||
| the `build.gradle.kts` file). If you want to publish elsewhere, you'll want to update that task. | ||
| [app.moderne.io](https://app.moderne.io) can draw recipes from the provided repository, as well as from [Maven Central](https://search.maven.org). | ||
|
|
||
| Note: | ||
| Running the publish task _will not_ update [app.moderne.io](https://app.moderne.io), as only Moderne employees can | ||
| add new recipes. If you want to add your recipe to [app.moderne.io](https://app.moderne.io), please ask the | ||
| team in [Slack](https://join.slack.com/t/rewriteoss/shared_invite/zt-nj42n3ea-b~62rIHzb3Vo0E1APKCXEA) or in [Discord](https://discord.gg/xk3ZKrhWAb). | ||
|
|
||
| These other docs might also be useful for you depending on where you want to publish the recipe: | ||
|
|
||
| * Sonatype's instructions for [publishing to Maven Central](https://maven.apache.org/repository/guide-central-repository-upload.html) | ||
| * Gradle's instructions on the [Gradle Publishing Plugin](https://docs.gradle.org/current/userguide/publishing\_maven.html). | ||
|
|
||
| ### From Github Actions | ||
|
|
||
| The `.github` directory contains a Github action that will push a snapshot on every successful build. | ||
|
|
||
| Run the release action to publish a release version of a recipe. | ||
|
|
||
| ### From the command line | ||
|
|
||
| To build a snapshot, run `./gradlew snapshot publish` to build a snapshot and publish it to Moderne's open artifact repository for inclusion at [app.moderne.io](https://app.moderne.io). | ||
|
|
||
| To build a release, run `./gradlew final publish` to tag a release and publish it to Moderne's open artifact repository for inclusion at [app.moderne.io](https://app.moderne.io). | ||
|
|
||
| ## Applying OpenRewrite recipe development best practices | ||
|
|
||
| We maintain a collection of [best practices for writing OpenRewrite recipes](https://docs.openrewrite.org/recipes/recipes/openrewritebestpractices). | ||
| You can apply these recommendations to your recipes by running the following command: | ||
|
|
||
| ```bash | ||
| ./gradlew rewriteRun -Drewrite.activeRecipe=org.openrewrite.recipes.OpenRewriteBestPractices | ||
| ``` | ||
| or | ||
| ```bash | ||
| ./mvnw -U org.openrewrite.maven:rewrite-maven-plugin:run -Drewrite.recipeArtifactCoordinates=org.openrewrite.recipe:rewrite-recommendations:RELEASE -Drewrite.activeRecipes=org.openrewrite.recipes.OpenRewriteBestPractices | ||
| ``` | ||
