Question

有两个非常相似的问题here和here。我使用play new创建了一个项目并运行play idea。测试使用play test命令运行，当我尝试在IDEA中运行它时，我得到以下堆栈跟踪。

我尝试在设置（IDE）中关闭外部编译器服务器 - ＆gt; Scala，使缓存无效，并获得相同的异常。这是关于编译器服务器的jetbrains post。

Answer 1

在我的情况下，133.331没有解决问题。 IntelliJ 13仍然无法编译测试代码。

我认为这是由于外部构建，因为IntelliJ 12没有外部构建选项关闭的问题。

Answer 2

将IntelliJ从13.0.1 133.330更新到13.0.1 133.331为我解决了这个问题。

在Intellij IDEA 13中播放框架2运行单元测试
