Fixes #245.
As
scala-collection-migrations
was not a part of the 2.1.2 release, this PR removes all mention of a 2.1.2 version ofscala-collection-migrations
in the README. Instead, it updates installation instructions to 2.1.1, which I suppose is the only way to mitigate the issue raised in #245.This PR is related to #264, which fixed the instructions for the
Collection213Upgrade
rewrite, but not for theCollection213CrossCompat
rewrite.I also added a line with
addCompilerPlugin(scalafixSemanticdb)
. The scalafix instructions mandate using this, but the instructions here don't contain the line. While the README does say to follow the installation instructions in scalafix, I think it makes for a better user experience to outline the steps here too.With these updated instructions, I was able to run the migration rules without errors on my project.
