[sbt 1.4.0] ClassCastException: sbt.internal.inc.MappedVirtualFile cannot be cast to java.io.File

I get this when running in my project.
It didn't used to happen; it happens when I update sbt to 1.4.0-RC1. Downgrading back to 1.3.10 makes the error stop

my guess is this code here is affected - https://github.com/cb372/sbt-explicit-dependencies/blob/master/src/main/scala-sbt-1.0/explicitdeps/package.scala
I think there's a reflection workaround that should work for both pre sbt 1.4 and 1.4
