io/src/main/scala/sbt/io/Using.scala:15:8: This wildcard import imports java.io.IO, which is shadowed by sbt.io.IO.
[error] This is not according to the language specification and has changed in Scala 2.13, where java.io.IO takes precedence.
[error] To keep the same meaning in 2.12 and 2.13, un-import IO by adding `IO => _` to the import list.
[error] import java.io._
[error]        ^
[error] one error found
[error] (io / Compile / compileIncremental) Compilation failed
