Importing scala3 library to build

[aronbergurj99]

I am trying to import local scala3 library to my build to handle code generation.

package build
import mill._, scalalib._
import $ivy.`org.example:gen_3:0.0.1`

I am able locate the library in $HOME/.ivy2/local but i get the following compilation error:

"error while loading Gen, Missing dependency 'Add -Ytasty-reader to scalac options to parse the TASTy in ..."

Does mill not support scala3 libraries?

Well I solved it by adding the option to scalacOptions in meta build but feels hacky:

    def scalacOptions = T {
        super.scalacOptions() ++ Seq("-Ytasty-reader")
    }

The next mill version 0.13 will be based on Scala 3, so you will be able to use Scala 3 libraries directly.

IMHO, that's a legit use of the meta-build.
