在IntelliJ13中编译Scala时擦除阶段出错

Question

当我运行SBT任务compile或Assembly时，我看不到任何编译器错误，并且得到了一个有效的JAR。当我从Intellij13.1.1#UI-135.480运行run配置时，我看到来自Scalac的以下错误。

我尝试运行SBT clean，使缓存无效，杀死所有nailgun运行者，重新启动IntelliJ idea。我现在总是看到这个错误。我以前也遇到过类似的问题，唯一的解决方法就是从我的计算机中删除所有IntelliJ文件并重新安装它。我希望这次不用那么做。在此之前，我将在Intellij12中尝试此操作。

唯一对我有帮助的是删除项目中的所有“目标”目录，并再次运行compile（没有帮助的步骤包括使缓存无效、重新加载project和运行clean)。
