斯卡拉克 : Assertion failed while run Scalatest in IDEA

Question

我在 Intellij IDEA 中运行 ScalaTest Suite，在 Scala 测试之前的 make 阶段，我遇到了这个问题:

Error:scalac: Error: assertion failed: List(object package$DebugNode, object package$DebugNode)

是不是由于增量编译导致的 jetbrains 错误？或者它与我正在运行的测试套件有关？堆栈跟踪中的任何信息都与我正在测试的 TestSuite/项目相关。

Answer 1

我认为这是由于 Interllij IDEA 增量编译导致的错误。我第一次构建 Spark 时遇到了同样的错误。

我去了 Preferences > Scala，设置了 SBT 增量编译器的增量编译，名称 Hasing:默认，编译顺序:Mixed。重新编译代码，然后一切正常。
