我正在尝试在 IntelliJ IDE 上设置 Scala，当我创建一个新项目时，它看起来很好。当我导入另一个项目时，它会出错：Extracting Structure Failed.
sbt shell 似乎在工作。可能是什么问题？
这是我的build.sbt：
course := "progfun1"
assignment := "example"
scalaVersion := "2.12.12"
scalacOptions ++= Seq("-language:implicitConversions", "-deprecation")
libraryDependencies += "com.novocode" % "junit-interface" % "0.11" % Test
testOptions in Test += Tests.Argument(TestFrameworks.JUnit, "-a", "-v", "-s")
这是日志：
