Scalac:在IDEA中运行Scalatest时断言失败

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:

由于增量编译,它是一个jetbrains错误吗？或者它与我运行的测试套件有关？堆栈跟踪中的任何信息都与我测试的TestSuite /项目无关.

Answer 1

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

我进入“首选项”>“Scala”，通过 SBT 增量编译器设置增量编译，名称 Hasing：默认，编译顺序：混合。重新编译代码，一切正常。
