Scalatra ドキュメント ( http://www.scalatra.org/2.2/guides/deployment/standalone.html ) の指示に従って「アセンブリ」コマンドを実行すると、次のエラーが発生します。

これは何を意味し、どのように修正できますか?

マージ戦略が最初に設定されている私のビルドファイルは次のとおりです。

まず、build.scala では、各行の間に空白行を入れる必要はありません。

次に、sbt-assembly の設定はプロジェクト設定の一部である必要があるため、Seq(...).

第三に、タイプが正しくないため、マージ戦略は機能しません。また、通常、すべてを最初に選択することはできません。次のようなものを試してください：

Seq(
  organization := Organization,
  name := Name,
  ....

  jarName in assembly := "scalatra_atmosphere_demo.jar",
  mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
    {
      case PathList(xs @ _*) if xs.last endsWith ".html" => MergeStrategy.first
      case x => old(x)
    }
  }
)
