PlayFramework項目與'activator run'一起使用，但部署dist不起作用

Question

我有一個playFramework2.4項目，當我使用「activator run」運行項目時它工作正常。

但是，當我分發「activator dist」，然後運行該應用程序時，它會發出錯誤。 似乎我有一些衝突的依賴關係，但我不知道爲什麼我在運行應用程序時看不到相同的問題。

Answer 1

事實證明，當我打電話給activator dist時，我得到了幾個其他的依賴導致衝突。

最後歸結爲試驗和錯誤，以找到所有問題。

我使用sbt-dependency-graph來查看依賴關係來自何處，還使用響應here來排除一些衝突的依賴關係。
