初めて localhost:9000 にアクセスするとエラーが発生します。これは私の最初の 'play run' コマンドです。私はプレイフレームワークが初めてで、ブラウザには次のように書かれています：問題を報告せずにコンパイルに失敗しました!?.
コントローラのコードはデフォルトです:
public class Application extends Controller {
public static Result index() {
return ok(index.render("Your new application is ready."));
}
}
プレイ2.0のバージョン。
ログファイルのスタックトレースは次のとおりです。
