Is there a tool for Scala to clean all the unused imports from all the code files? [closed]

Answer 1

IntelliJ can automatically clean up imports, not just highlight them, and for the whole directory. The shortcut is Ctrl + Alt + O.

Answer 2

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.

Answer 3

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"
