  <p>Am I using the wrong dependency? Why scala-library is not found? Here is my build:</p>
  
  <pre><code>apply plugin: 'java'
  apply plugin: 'scala'
  apply plugin: 'eclipse'
  
  repositories { mavenCentral() }
  
  dependencies {
      def hamcrestVersion = "1.3"
      def jmockVersion = "2.6.0"
      compile 'org.mongodb:mongo-java-driver:2.12.0-rc0',
              'org.mongodb.morphia:morphia:0.106',
              'org.scala-lang:scala-library:2.10.3',
              'org.scala-lang:scala-compiler:2.10.3'
  
      testCompile 'org.scalatest:scalatest_2.10:2.1.0',
              'junit:junit:4.11',
              'de.flapdoodle.embed:de.flapdoodle.embed.mongo:1.42',
              "org.hamcrest:hamcrest-core:${hamcrestVersion}",
              "org.hamcrest:hamcrest-library:${hamcrestVersion}",
              "org.jmock:jmock:${jmockVersion}"
      testCompile("org.jmock:jmock-junit4:${jmockVersion}") {
          exclude group: "junit"
      }
  }
