IntelliJ：类路径中缺少符号 'type org.scalatest.compatible.Assertion'答案

【问题描述】：

编写scala测试，遇到错误：

Symbol 'type org.scalatest.compatible.Assertion' is missing from the classpath.
This symbol is required by 'type org.scalatest.Assertion'.
Make sure that type Assertion is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
A full rebuild may help if 'package.class' was compiled against an incompatible version of org.scalatest.compatible.

我的 build.sbt 很简单：

import sbt.Keys.libraryDependencies

ThisBuild / scalaVersion     := "2.13.2"
ThisBuild / version          := "0.1.0-SNAPSHOT"
ThisBuild / organization     := "com.example"
ThisBuild / organizationName := "example"

lazy val root = (project in file("."))
  .settings(
    name := "myproj",
    libraryDependencies += "org.scalactic" %% "scalactic" % "3.2.9",
    libraryDependencies += "org.scalatest" %% "scalatest" % "3.2.9" % "test",
    libraryDependencies += "org.scalatest" %% "scalatest-funsuite" % "3.2.9" % "test",
    libraryDependencies += "org.scala-lang.modules" %% "scala-parser-combinators" % "1.1.2",
    )

仅当我在 IntelliJ 中构建项目时才会出现此问题。使用 sbt 本身可以很好地编译。

sbt version in this project: 1.3.10
sbt script version: 1.3.6

知道如何在 IntelliJ 中修复它吗？

【问题讨论】：

明显的建议但值得一提 - 你试过File -> Invalidate Caches吗？

【解决方案1】：

我解决了大部分与 IntelliJ 被破坏有关的问题：

sbt clean compile 在终端的根文件夹中
View -> Tool Windows -> sbt 和标签内Reload SBT project（右键单击项目）
