Gradle Scala Extras

This Gradle plugin aims to enhance the Scala Gradle core plugin with quality assurance tools and custom configurations.

Features

• Support for Scalafix and Scalafmt with a default configuration that can be overridden following the How to use section.
• Aggressive Scala compiler option to treat warnings as errors is applied by default (still configurable).
• Out-of-the-box configuration to generate aggregated subprojects scaladoc.

Other features may come in the future.

How to use

plugins {
    id("io.github.tassiluca.gradle-scala-extras") version "<SELECT THE VERSION>"
}

The plugin is configurable through the scalaExtras extension:

scalaExtras {
    qa { 
        allWarningsAsErrors = false
        scalafix {
            configFile = "stringified path to the scalafix configuration"
        }
        scalafmt {
            configFile = "stringified path to the scalafmt configuration"
        } 
    }
}

• allWarningsAsErrors is a boolean property that allows to disable the aggressive compiler option to treat warnings as errors;
• configFile is a string that allows to set the path to the Scalafix / Scalafmt configuration file;
  • if not set, the plugin will search for a .scalafix.conf / .scalafmt.conf file in the project root directory. If not found, the default configuration is applied;
  • Default configurations can be found here.

Moreover, the plugin adds the following tasks to the project:

• format to automatically format the Scala source code adhering to the QA supported tools;
• aggregateScaladoc to generate the aggregated scaladoc for all the subprojects, including the root one. Generated documentation is placed in the root project build/docs/aggregated-scaladoc directory.
