IntelliJ 可以自动清理导入，而不仅仅是突出显示它们，而且可以清理整个目录。快捷键是Ctrl + Alt + O。
Ctrl + Alt + O
IntelliJ can automatically clean up imports, not just highlight them, and for the whole directory. The shortcut is Ctrl + Alt + O.
我认为 Intellij 将未使用的导入标记为灰色。我认为还没有一个自动工具。 Eclipse 和 ensime 的“组织导入”重构不会删除导入。当然，您始终可以注释掉各个导入并重新编译。
I think Intellij marks unused imports gray. I don't think there is an automatic tool yet. Eclipse's and ensime's "organize imports" refactoring doesn't remove imports. You could of course always comment out individual imports and recompile.
Scalafix 进行了重写，以删除未使用的导入： https://scalacenter.github.io/scalafix/#RemoveUnusedImports
添加 addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.5.0-M1") 到您的project/plugins.sbt
addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.5.0-M1")
，然后运行sbt "scalafix RemoveUnusedImports"
sbt "scalafix RemoveUnusedImports"
Scalafix has a rewrite to remove unused imports: https://scalacenter.github.io/scalafix/#RemoveUnusedImports
add addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.5.0-M1") to your project/plugins.sbt
then run sbt "scalafix RemoveUnusedImports"
