Synopsis

A wrapper that allows the use of the Scalafmt formatter in Maven.

Usage

Add the following snippet to your pom, and it will be invoked as part of your build during the selected lifecycle phase (default validate).

Note: version.scala.binary refers to major releases of scala ie. 2.11, 2.12 or 2.13.
mvn_scalafmt_2.11 will soon be deprecated and may not receive future releases

You can also invoke the plugin directly via mvn scalafmt:format.

Versioning

This plugin follows the following versioning convention:

mvn_scalafmt_(scalaversion)-(major).(minor).(commitepoch).(commithash)

The latest release should be visible at the top of this readme.

Minimal Working POM XML:

    <plugin>
        <groupId>org.antipathy</groupId>
        <!-- The scala binary here doesn't need to match the project version -->
        <artifactId>mvn-scalafmt_${version.scala.binary}</artifactId>
        <!-- This represents the desired version of the plugin, whould be in the form:
             (major).(minor).(commitepoch).(commithash), which can be found here:
             https://github.com/simonjpegg/mvn_scalafmt/releases
             e.g. <version>1.0.1589620826.41b214a</version>
             Note: The SCALA version is OMITTED from this value
        -->
        <version>__DESIRED_MVN_SCALAFMT_VERSION__</version>
        <configuration>
            <configLocation>${project.basedir}/.scalafmt.conf</configLocation> <!-- path to config -->
        </configuration>

                </goals>
            </execution>

configLocation Can either be a local path (e.g. ${project.basedir}/.scalafmt.conf) or a HTTP url (e.g https://raw.githubusercontent.com/jozic/scalafmt-config/master/.scalafmt.conf)

make sure you have set a version in your scalafmt.conf

version = "2.6.2"
