Purpose

This preset adds the ability for Renovate to suggest upgrades to the Scalafmt version set in Maven Spotless plugin.

As Renovate natively supports upgrading version in the Scalafmt configuration file, this preset will include the changes to the pom.xml file in the same PR/MR as the .scalafmt.conf file.

Example

This preset will suggest changes similar to the following:

pom.xml:

<plugin>
  <groupId>com.diffplug.spotless</groupId>
  <artifactId>spotless-maven-plugin</artifactId>
  <version>2.46.1</version>
  <configuration>
      <scala>
        <scalafmt>
-            <version>3.9.7</version>
+            <version>3.9.8</version>
            <file>${project.basedir}/.scalafmt.conf</file>
        </scalafmt>
      </scala>
  </configuration>
</plugin>
