? ? ? ?最近在自學scala，scala默認用的不是maven用的是sbt所以就嘗試在idea中嘗試建立sbt的項目逆济。最初遇到很多問題酌予，下面是我發(fā)現(xiàn)的其中之一。
第一次嘗試在新建項目的時候我選擇了sbt和scala都不是我本機安裝的版本奖慌，
結果就出現(xiàn)下面這樣的錯誤：
[error] sbt.librarymanagement.ResolveException: Error downloading org.jetbrains:sbt-structure-extractor;sbtVersion=1.0;scalaVersion=2.12:2018.2
[error]? Not found

在這里要提醒下抛虫，我們在新建項目的時候一定要先查看本地安裝的sbt和scala版本可以通過sbt about查看：
在新建項目的時候選擇上面的sbt和scala版本就不會出現(xiàn)各種奇怪的問題了。
