scala - 如何修复 sbt 项目中的 "origin location must be absolute"错误(使用 Spark 2.4.5 和 DeltaLake 0.6.1)？

Question

我正在尝试使用 DeltaLake 0.6.1 为 Spark 2.4.5 设置 SBT 项目。我的构建文件如下。
但是似乎此配置无法解决某些依赖项。

有关如何解决此问题的任何提示？

Answer 1

我还没有设法弄清楚它何时以及为什么发生，但我早些时候确实遇到过类似的与分辨率相关的错误。
每当我遇到像您这样的问题时，我通常会删除受影响的目录(例如 /Users/ashika.umagiliya/.m2/repository/org/antlr )并重新开始。它通常有帮助。如果没有，我删除~./ivy2也重新开始。这是一种大锤，可以完成工作(又名 if all you have is a hammer, everything looks like a nail )。
我总是确保使用最新最好的 sbt。你似乎在使用 macOS 所以使用 sdk update早和经常。
我还建议使用最新和最好的库版本，更具体地说，Spark 应该是 2.4.7(在 2.4.x 行中)，而 Delta Lake 应该是 0.8.0。
