Custom scalar does not allow generics

[cvb941]

Version

4.0.0

Summary

I'm trying to setup an adapter for a Mass measurement from a float.

mapScalar("Mass", "io.nacular.measured.units.Measure<Mass>", "data.apollo.MassAdapter")

Notice that the target class has a type parameter.

Gradle sync fails with the following error: Can't escape identifier `Measure<Mass>` because it contains illegal characters: <>

This is the adapter (for completeness):

val MassAdapter = object : Adapter<Measure<Mass>> {
    override fun fromJson(reader: JsonReader, customScalarAdapters: CustomScalarAdapters): Measure<Mass> {
        val weightDouble = reader.nextDouble()
        return weightDouble.asMass(Mass.baseUnit)
    }

    override fun toJson(writer: JsonWriter, customScalarAdapters: CustomScalarAdapters, value: Measure<Mass>) {
        writer.value(value.`in`(Mass.baseUnit))
    }
}

Steps to reproduce the behavior

Thanks for reporting this! We may be able to support this in the future but in the meantime a simple solution is to use a typealias:

typealias MassMeasure = Measure<Mass>

mapScalar("Mass", "data.apollo.MassMeasure", "data.apollo.MassAdapter")
