PlayFramework项目与“activator run”配合使用，但部署的dist不起作用

Question

我有一个playFramework2.4项目，当我使用“activator run”运行该项目时，它运行良好。

然而，当我分发“activator dist”，然后运行应用程序时，它会给出一个错误。看起来我有一些相互冲突的依赖项，但我不知道为什么在运行应用程序时没有看到同样的问题。

Answer 1

事实证明，当我调用激活器dist时，我得到了其他几个导致冲突的依赖项。

最后需要反复试验才能找到所有问题。

我使用了sbt-依赖关系-图来查看依赖关系的来源，并在此处使用响应来排除一些冲突的依赖关系。
