Playframwork 2.5创建后无法编译“播放java种子”应用程序

Question

我正在按照本教程尝试播放框架2.5.4：

https://www.playframework.com/documentation/2.5.x/Installing

我使用“Play Scala Seed”模板创建了一个应用程序，它运行正常。

但是当我从“Play Java Seed”模板创建一个应用程序时，它无法编译。

我尝试阅读错误消息，但我没有提示解决此问题。

这是详细错误消息：

我正在使用：

1. Windows 7
2. Java 8
3. 活化剂 - DIST-1.3.10
4. 播放2.5.4

如何解决这个问题？
