Playフレームワークを使っているのですが、コンパイル時に下記のようなエラーが出てしまいます。 書いてある通り「last
compile:compile」も試しましたが、スタックトーレースに自分の書いたソースファイルは無く、原因がわかりません。 どなたか分かりますでしょうか？？

[code]

    activator
    [XXXXXX] $ compile
    [info] Compiling 84 Scala sources and 2 Java sources to > /XXX/target/scala-2.11/classes...
    [trace] Stack trace suppressed: run last compile:compile for the full output.
    [error] (compile:compile) java.lang.NullPointerException
    [error] Total time: 4 s, completed 2014/12/18 18:28:57
    
[/code]

下記「last compile:compile」の内容です。

全く原因分からないんですが、これで通る、通らないが変わるようです。

コンパイルが通る

[code]

    ◯ case class Report[A](key: Int, data: A)
    
[/code]

コンパイルが通らない

[code]

    × case class Report[A](key: String, data: A)
    
[/code]

question
scala playframework
Scala-Playのコンパイル時に、詳細が表示されないコンパイルエラーが出ます・・


完全に原因分かりました。

コンパイルが通る

[code]

    case class Report[A](key: Int, data: A)
    
[/code]

通らない

[code]

    case class Report[A](key: String, data: A)
    
[/code]

だったのですが、別の場所でこういったimplicit defを定義しておりました。

[code]

      implicit def reportExtractor[A](implicit extractor: Extractor[A, Json]): Extractor[Api.Report[A], Json] = BasicExtractor { x =>
        val js = x.asInstanceOf[Json]
        Api.Report(js.id.as[Int], js.data.as[A])
      }
    
[/code]

そして、この「Extractor[A, Json]」がrapture内のマクロで生成されるため、エラーがimplicit defではなく、case
class実装側で出ていました。 sbtのバグではなかったです。

（ただ、このマクロ実装側でエラーが出て、しかもなんだかよく分からないログしか出ないという仕様を何とかしてほしいなぁ、と思いました）

コメント頂いた方、ありがとうございました。
