Gradle Twirl Templates Plugin

A Gradle plugin to provide Twirl template compilation and integration for your projects.

Install

To use the Gradle plugin, just add the following to your build.gradle file.

buildscript {
  repositories {
    	mavenCentral()
	maven {
		url "http://oss.sonatype.org/content/repositories/snapshots/"
	}
  }
  dependencies {
    classpath "us.hexcoder:gradle-twirl:1.0.0-SNAPSHOT"
  }
}

apply plugin: "twirl"

If you are using the Twirl templates with Java, you will need to enable Scala's joint-compilation by assigning all Java source directories to the Scala sourceSet and setting the Java sourceSet to be empty. Here is a default configuration:

apply plugin: "scala"

sourceSets {
	// See: http://forums.gradle.org/gradle/topics/how_to_compile_a_java_class_that_depends_on_a_scala_class_in_gradle
	main {
		scala {
			srcDir "src/main/java"
		}

		java {
			srcDirs = []
		}
	}
}

Customization

The plugin should work out-of-the-box for most users. All you need are your source templates under src/main/twirl for the templates to be picked up and compiled. If the defaults are not sufficient for you, you can use the plugin configuration to tweak things to your liking.

twirl {
	sourceDirectory = "src/main/twirl"
	testSourceDirectory = "src/test/twirl"
	targetDirectory = "build/generated-sources/main/twirl"
	testTargetDirectory = "build/generated-sources/test/twirl"
	imports = ["java.lang._", "java.util._", "scala.collection.JavaConversions._", "scala.collection.JavaConverters._"]
	charset = "UTF8"
}

Tasks

The plugin makes two tasks available, compileTwirl and compileTestTwirl. These commands work in the same way that commands like compileJava or compileTestGroovy would work. They compile from the source or test directories respectively and output them into the appropriate directory. These tasks will be run before the compileScala or compileTestScala tasks as available and as needed.
