scala - 什么 lmcoursier.internal.shaded.coursier.error.FetchError$DownloadingArtifacts : Error fetching artifacts: means?

Question

我从 github 得到了这个项目，文件中的导入行 build.sbt被红了。

我有 scala 2.11.11 , sbt 1.3.4在本地，

然后我在idea中通过sbt模式导入项目，并获取这个错误

那是什么意思？我该怎么办？

Answer 1

通过 sbt 导入 Spark SQL 包时，我也遇到了同样的问题。在 spark-sql 中有多个文件夹，即 spark-sql 2.12 和 spark-sql 2.11。当我删除它们并刷新 build.sbt 时，问题得到解决。

在此路径中 C:\Users\TF\AppData\Local\Coursier\cache\v1\https\repo1.maven.org\maven2\org\scala-lang\scala-compiler\同一个包的不同版本可能有多个文件夹。全部删除并刷新 build.sbt .问题应该得到解决。
