[scala][sbt]プラグインの利用方法

Contents

目的

Scala Sbt でプラグインを使う方法のメモ。
Googleで検索しても門外漢用の記事がなくて苦労したため、メモしてみた。

環境

  • OS
    • Linux www4322gi 3.2.0-64-generic #97-Ubuntu SMP Wed Jun 4 22:04:21 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
  • Scala
    • version: 2.10.4

事前準備

ScalaとSbtを以下を参考にインストールする。

ディレクトリ構成

pwd

~/hello

├── build.properties
├── build.sbt
└── src
    ├── main
    │   └── scala
    │       └── com
    │           └── example
    │               └── hello
    │                   └── Hello.scala
    └── test
        └── scala
            └── com
                └── example
                    └── hello
                        └── HelloTest.scala

11 directories, 4 files

Hello.scala

Command


mkdir -p src/main/scala/com/example/hello
mkdir -p src/test/scala/com/example/hello

Hello.scala

package com.example.hello

import breeze.linalg._

object Hello {
  def main(args: Array[String]) {
    val m23 = DenseMatrix(
      (1.0d, 2.0d, 3.0d),
      (4.0d, 5.0d, 6.0d))

    val plusall = m23 + 0.1d

    println(m23)
    println(plusall)
  }
}

HelloTest.scala

package com.example.hello

import org.scalatest.FunSuite

class HelloTest extends FunSuite {
  test("Hello should run main") {
    expectResult()(Hello.main(Array.empty))
  }
}

ビルド設定

build.properties

sbt.version=0.13.5

build.sbt

name := "hello"

version := "1.0"

scalaVersion := "2.10.4"

libraryDependencies += "org.scalatest" % "scalatest_2.10" % "1.9.1" % "test"

libraryDependencies  ++= Seq(
            "org.scalanlp" % "breeze_2.10" % "0.5.2"
)

resolvers ++= Seq(
            "Sonatype Snapshots" at "https://oss.sonatype.org/content/repositories/releases/"
)
