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。

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

val plusall = m23 + 0.1d
println(m23)
println(plusall)
}
}

package com.example.hello
import org.scalatest.FunSuite
class HelloTest extends FunSuite {
test("Hello should run main") {
expectResult()(Hello.main(Array.empty))
}
}
