play2-elasticsearch示例與play2.1.3不兼容

Question

我正在試圖使用Play2-elasticsearch插件for playframework2版本2.1.3 我剛剛完成了github示例的說明，唯一的修改是將此行更改爲在本地IP地址上使用服務器。

elasticsearch.client="127.0.0.1:9300" 

但是當我嘗試運行該示例時，我得到以下異常，任何想法？ 我使用播放框架2.1.3在Mac上使用jdk1.7

從堆棧跟蹤，似乎您使用0.5.4版本，這是不玩2.1.3（僅能夠播放2.1兼容.0）。

如果您查看自述文件中的"versions" table，您會發現如果使用play 2.1.3，則需要0.7-SNAPSHOT版本。嘗試使用這一個。
