DuplicateMemberException播放框架mongodb模塊

我開始播放應用程序時出現此錯誤。我使用Play 1.2.4和Mongo 1.3模塊。DuplicateMemberException播放框架mongodb模塊

`Oops: DuplicateMemberException

我的類看起來像

}

老實說，我強烈建議您嘗試使用PlayMorphia插件來替換Mongodb插件。檢查它在：http://www.playframework.org/modules/morphia – 2012-02-16 19:10:44

看起來像你的項目包括蒙戈模塊不止一次。你是如何聲明mongo模塊的？不要在applicaiton.conf和dependencies.yml中聲明它。
