intelliJ "unknown artifact. Not resolved or indexed" for scalatest with scala 2.13.1, sbt 1.3.3

Question

IntelliJ 中的以下组合给出了 "unknown artifact" 错误。

scala 2.13.1
Java 13 JDK
sbt 1.3.3

以下组合不报错

scala 2.12.10
Java 13 JDK
sbt 1.3.3

来自类似问题的建议没有帮助：

File/InvalidateAndRestart
"update project resolvers' index"

我错过了什么？

更新 2：

以下组合和步骤对我有用

scala 2.13.1
Java OpenJDK 13.0.1（将 IntelliJ sbt 选项设置为 OpenJDK）
sbt 1.3.3（将 IntelliJ sbt-launch.jar 选项设置为 sbt 1.3.3 目录）

步数：

在命令行中创建一个新的示例项目（参见 https://www.scala-sbt.org/1.x/docs/sbt-by-example.html）
sbt 编译，测试应该可以工作
在 IntelliJ 中导入这个项目

IntelliJ 仍然显示 "unknown artifact" 消息，但 sbt 编译、测试有效。

我假设新安装的 IntelliJ 在为 Cousier 编译 scala2_12 桥时遇到问题。

命令行重新编译，现在在项目目录下scalatest_2.13可以看到之前没有的

Answer 1

以下组合和步骤对我有用

scala 2.13.1
Java OpenJDK 13.0.1 (set IntelliJ sbt options to OpenJDK)
sbt 1.3.3 (set IntelliJ sbt-launch.jar option to sbt 1.3.3 directory)

步骤：

create a new sample project in commandline (see https://www.scala-sbt.org/1.x/docs/sbt-by-example.html)
sbt compile, test should work
import this project in IntelliJ

IntelliJ 仍然显示“未知工件”消息，但 sbt 编译、测试有效。
