Question

我无法调试（简单运行正常）我的单元测试。 Squeryl失败，但有以下异常：

error while reflecting on metadata for (Some(private scala.Option
com.company.play.model.db.mapping.Position.orgUnit2id),Some(public scala.Option
com.company.play.model.db.mapping.Position.orgUnit2id()),None,Set(@org.squeryl.annotations.ColumnBase(optionType=class java.lang.Object, name=, length=-1, scale=-1, value=ORG_UNIT2ID))) of class com.company.play.model.db.mapping.Position

我使用IntelliJ IDEA最新版本（13.1.4）进行调试。在IDEA和＆amp ;;在控制台（sbt clean编译测试）工作正常。

从jdk 1.8切换到jdk 1.7解决了这个问题。

Squeryl无法仅在调试模式下反映出来
