java - 游戏测试失败(游戏框架 2.2.2)

Question

刚刚习惯了 Play Framework 并设置了一个新的 Web 应用程序。

我想做一些模型单元测试，但是当我运行 play test 时，我收到以下错误消息:

[Opinions] $ test
[trace] Stack trace suppressed: run last *:testListeners for the full output.
[error] (*:testListeners) java.net.UnknownHostException: linux-hkem.site: linux-hkem.site: Der Name oder der Dienst ist nicht bekannt
[error] Total time: 10 s, completed 12.04.2014 21:42:35

Der Name oder der Dienst ist nicht bekannt 是德语，意思是:

名称或服务无法识别

linux-hkem 是我的电脑名称。这似乎不是代码错误，而是配置错误。谁能帮我解决这个问题？

这是完整的堆栈跟踪:

play run 运行得非常好，以防有人疑惑。

修正了这个编辑我的主机文件的问题:

echo "127.0.0.1 localhost linux-hkem.site" >> /etc/hosts

感谢:

Why does java.net.UnknownHostException require changes to the hosts file?
