This is a simple Scala build in Gradle. This particular build file ships with the Gradle distribution and it shows how declarative Gradle can be.

build.gradle

apply plugin: 'eclipse'
apply plugin: 'scala'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.scala-lang:scala-library:2.9.1'
}

dependencies {
    compile 'commons-collections:commons-collections:3.2'
    testCompile 'junit:junit:4.11'
}
