Question

我无法在我的sbt项目中为scala解析LOG4j的依赖关系。我有一个具有相同依赖关系和相同scala版本的maven项目，它运行良好。这是我的build.sbt

scalaVersion := "2.11.8"

libraryDependencies += "org.apache.logging.log4j" %% "log4j-core" % "2.7"

libraryDependencies += "org.scalactic" %% "scalactic" % "3.0.1"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.1" % "test"

这是IntelliJ向我显示的错误

Answer 1

只需将%%替换为log4j依赖关系中的%，以便它变为

   libraryDependencies += "org.apache.logging.log4j" % "log4j-core" % "2.7"

请参阅Build.scala, % and %% symbols meaning了解相关信息。

由于log4j是java库，因此它不包含工件坐标中的scala版本。
