No TypeLiteral for types taking a slick.dbio.DBIO as type parameter can be created

[carstenlenz]

Hi,

doing something like in this example:

import com.google.inject.Guice
import net.codingwell.scalaguice.InjectorExtensions.ScalaInjector
import net.codingwell.scalaguice.ScalaModule
import slick.dbio.DBIO

import scala.util.Try

object ModuleTesting {
  def main(args: Array[String]): Unit = {
    val injector = Guice.createInjector(new TestModule)
    val inst     = injector.instance[MyTF[Try]]
    val inst2     = injector.instance[MyTF[DBIO]]
  }
}

class TestModule extends ScalaModule {
  override def configure(): Unit = {
    bind[MyTF[Try]]
    bind[MyTF[DBIO]]
  }
}

class MyTF[F[_]] {}

gives the following error:

java.lang.UnsupportedOperationException: Could not convert scalaType slick.dbio.DBIO to a javaType: scala.reflect.internal.Types$AliasNoArgsTypeRef

        ...

As a workaround either constructing TypeLiterals manually (new TypeLiteral[MyTF[DBIO]] {}) or using @Provide methods works.
