私は、ルートプロジェクトが単純なSBTプロジェクトであるマルチプロジェクトで、Play Frameworkを使用する方法に関する情報を見つけるのに苦労しています。基本的に、これは私のプロジェクトのレイアウトです：複数のプロジェクトでPlay Frameworkを使用するにはどうすればよいですか？

my-play-project/runをSBTコンソールで実行してアプリケーションを起動できますが、ページには、私は500を取得し、このエラーが記録されます。

は、このプロジェクトを壊す私が行方不明です明白なものはありますか？コントローラは、マニュアルで説明されているように、最も簡単な方法で定義されています。同じことは、私が提供する唯一のルートのために行く：私はフレームワーク2.5.1およびプロジェクトのビルドを再生使用してい

同様のマルチプロジェクトビルドを手に入れることはできませんでした以下の答えを使って作業してください。しかし、 [Marius Soutierのマルチプロジェクトサンプルプロジェクトを再生]（https://github.com/mariussoutier/play-multi-multi-project）を詳しく見てみると非常に役に立ちました。 私のケースでは、 'scalaVersion'をすべてのサブプロジェクトに伝播するために' thisBuildでscalaVersionを使うのを忘れてしまいました。 –
