Scalafmt plugin for maven

Synopsis

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

Note: There are multiple versions of the plugin released and the version of the plugin should match the version of scalafmt you wish to use. Current supported versions are 0.6.8 - 1.3.0. For example, to use the latest version of the plugin with the latest version of scala-fmt you should set the version to 0.5_1.3.0 in your pom. All versions are currently compiled against Scala 2.11.8. If you require anything else (such as support for a newer Scalafmt release), please open an issue.
