This project contains migration rules to upgrade scalafix.g8 generated builds to use the latest Scalafix v0.6 APIs. At the root of your scalafix.g8 generated build, run this migration
export _JAVA_OPTIONS=-Xss1515m # a large stack size is required for the Scala compiler
coursier launch ch.epfl.scala:scalafix-cli_2.12.6:0.6.0-M9 --main scalafix.cli.Cli -- -r github:scalacenter/scalafix.g8/v0.6 --verbose
The rewrite is syntactic and does a best-effort to migrate both *.scala and
*.sbt files.
The rule may not work as expected if you have customized the auto-generated
build.sbt and test suite.
Running the rewrite should produce a diff like this:
