I get a build error when using gRPC Monix with ScalaPB 0.8.1:

[...]/grpc-monix-sample/build.sbt:21: error: Symbol 'type scalapb.compiler.DescriptorPimps' is missing from the classpath.
This symbol is required by 'class grpcmonix.generators.GrpcMonixGenerator'.
Make sure that type DescriptorPimps is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
A full rebuild may help if 'GrpcMonixGenerator.class' was compiled against an incompatible version of scalapb.compiler.

Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?
I've attached a minimal project that you can use to reproduce the above:
grpc-monix-minimal.zip
The current generated code for bindService
calls:
ServerServiceDefinition
.builder("the.name.of.the.Service")
...
While this works, it doesn't register the service in a way that the ProtoReflectionService
can see.
The generated code already has a ServiceDescriptor that properly describes the service:
val SERVICE: _root_.io.grpc.ServiceDescriptor = ...
If bindService
is changed to call this instead, reflection works:
ServerServiceDefinition
.builder(SERVICE)
...
Setting ScalaPB's flatPackage
to true causes compilation of generated Scala source to fail:
PB.targets in Compile := Seq(
scalapb.gen(grpc = true, flatPackage = true) -> (sourceManaged in Compile).value,
grpcmonix.generators.GrpcMonixGenerator -> (sourceManaged in Compile).value
)
Sample error:
[error] /Users/shane/node/app/target/scala-2.12/src_managed/main/mu/node/api/user/UserGrpcMonix.scala:19: object SignUpRequest is not a member of package mu.node.user
[error] new Marshaller(mu.node.user.SignUpRequest),
[error] ^
This while compiling a file called user.proto
.
Could you update grpcmonix to use scalapb v0.6.7 and sbt-protoc v0.99.13?
Great project by the way!
It would be nice to update to the version of monix in which this project is depending on. If there is not an actual plan to work on that, I can do it by myself.
