How to install compiler plugin and full cross-version Scala dependencies?

[tindzk]

Thanks for positive feedback and bringing up these issues, @olafurpg!

How do I add a compiler plugin?

There is no syntax yet for defining compiler plug-ins. For the Scala.js and Scala Native, the logic was hard-coded. But for Macro Paradise and other plug-ins, we need a more generic approach such as:

compilerDeps = [
  ["org.scalamacros", "paradise", "2.1.1", "full"]
]

This would behave like scalaDeps, but also add the -Xplugin parameter.

How do I add Scala dependencies that are cross-versioned against the full Scala compiler version? A workaround is to update javaDeps like this

I was not aware of this use case. We could add a fourth parameter which defaults to binary to retain the current behaviour. Then, you could write:

scalaDeps = [
  ["org.scalameta", "interactive", "4.1.0", "full"]
]

This should not be too hard to implement since the logic is already in place and only needs to be exposed in the TOML format.

I implemented both features in #8 and #9. Feel free to try the latest snapshot version and report any issues you encounter.
