Eliminate Tech-Debt. At build time.

What is this?

This project provides a Maven plugin that applies Rewrite checking and fixing tasks as build tasks, one of several possible workflows for propagating change across an organization's source code.

Getting started

This README may not have the most up-to-date documentation. For the most up-to-date documentation and reference guides, see:

To configure, add the plugin to your POM:

<?xml version="1.0" encoding="UTF-8"?>
<project>
    ...
    <build>
        <plugins>
            <plugin>
                <groupId>org.openrewrite.maven</groupId>
                <artifactId>rewrite-maven-plugin</artifactId>
                <version><!-- latest version here --></version>
                <configuration>
                    <activeRecipes>
                        <recipe>org.openrewrite.java.format.AutoFormat</recipe>
                    </activeRecipes>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

If wanting to leverage recipes from other dependencies:

<?xml version="1.0" encoding="UTF-8"?>
<project>
    ...
    <build>
        <plugins>
            <plugin>
                <groupId>org.openrewrite.maven</groupId>
                <artifactId>rewrite-maven-plugin</artifactId>
                <version><!-- latest version here --></version>
                <configuration>
                    <activeRecipes>
                        <recipe>org.openrewrite.java.testing.junit5.JUnit5BestPractices</recipe>
                        <recipe>org.openrewrite.github.ActionsSetupJavaAdoptOpenJDKToTemurin</recipe>
                    </activeRecipes>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.openrewrite.recipe</groupId>
                        <artifactId>rewrite-testing-frameworks</artifactId>
                        <version><!-- latest dependency version here --></version>
                    </dependency>
                    <dependency>
                        <groupId>org.openrewrite.recipe</groupId>
                        <artifactId>rewrite-github-actions</artifactId>
                        <version><!-- latest dependency version here --></version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>
</project>

To get started, try mvn rewrite:help, mvn rewrite:discover, mvn rewrite:dryRun, mvn rewrite:run, among other plugin goals.

See the Maven Plugin Configuration documentation for full configuration and usage options.

Snapshots

To use the latest -SNAPSHOT version, add a <pluginRepositories> entry for OSSRH snapshots. For example:

<?xml version="1.0" encoding="UTF-8"?>
<project>
    ...
    <build>
        <plugins>
            <plugin>
                <groupId>org.openrewrite.maven</groupId>
                <artifactId>rewrite-maven-plugin</artifactId>
                <!-- Use whichever version is latest at the time of reading. This number is a placeholder. -->
                <version>4.17.0-SNAPSHOT</version>
                <configuration>
                    <activeRecipes>
                        <recipe>org.openrewrite.java.logging.slf4j.Log4j2ToSlf4j</recipe>
                    </activeRecipes>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.openrewrite.recipe</groupId>
                        <artifactId>rewrite-testing-frameworks</artifactId>
                        <!-- Use whichever version is latest at the time of reading. This number is a placeholder. -->
                        <version>1.1.0-SNAPSHOT</version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>

    <pluginRepositories>
        <pluginRepository>
            <id>ossrh-snapshots</id>
            <url>https://oss.sonatype.org/content/repositories/snapshots</url>
        </pluginRepository>
    </pluginRepositories>

</project>

Notes for developing and testing this plugin

This plugin uses the Maven Integration Testing Framework Extension for tests.

All tests can be run from the command line using:

./mvnw verify

If you're looking for more information on the output from a test, try checking the target/maven-it/**/*IT/** directory contents after running the tests. It will contain the project state output, including maven logs, etc. Check the Integration Testing Framework Users Guide for information, too. It's good.

Using this plugin against itself

The pom.xml file contains a bootstrap profile to use the rewrite-maven-plugin against itself (it's a helpful plugin, why not use it to help develop itself?).

./mvnw -Pbootstrap rewrite:dryRun
