Strange missing implicit compilation error

[Pierre1405]

Hello,

I had a very surprising compilation error with an even more surprising work around, I have 2 case class case class DeviceMessage(rinfos: List[ReceiverInfo]) case class ReceiverInfo(isNew: Option[Boolean] = Some(false))

and with the following code import java.io.ByteArrayOutputStream import com.sigfox.das.avro.models.v3.commons.models.device.DeviceMessage import com.sksamuel.avro4s.AvroOutputStream

class AvroProducerMessagePrintLn { val baos = new ByteArrayOutputStream() val output = AvroOutputStream.binary[DeviceMessage](baos) } I have this compilation error: Could not find implicit SchemaFor[com.sigfox.das.avro.models.v3.commons.models.device.DeviceMessage] val output = AvroOutputStream.binaryDeviceMessage

I found a workaround by replacing import com.sigfox.das.avro.models.v3.commons.models.device.DeviceMessage by import com.sigfox.das.avro.models.v3.commons.models.device.{ DeviceMessage, ReceiverInfo }

I think it's a scala compilation error and I'm not sure there is some way for you to avoid this error, but I thought I'm may be interesting to know this problem

I attach to the ticket a sbt project if you want to reproduce it or do more test. avro4sCompilationError.tar.gz

Thanks anyway for your work on avro4s

Regards, Pierre

Just ran into this when updating to 1.9.0 from 1.8.3. Thanks for documenting this bug and the workaround!

Side note: change log for 1.9.0 would be nice
