Mutiny service interface cannot be injected - grpc

Question

im struggling implementing gRPC communication.
There is one maven project with two modules which should communicate using gRPC.
The classes generated from *.proto-files contains SessionServiceInterface, which is in fact a MutinyService-interface. (partial implementation below)
Running both projects results in the following Error:
Caused by: javax.enterprise.inject.spi.DeploymentException: de.ilem0n.SessionServiceInterface cannot be injected into de.ilem0n.sessions.FlinkSessionReconciler#sessionService - only Mutiny service interfaces, blocking stubs, reactive stubs based on Mutiny and io.grpc.Channel can be injected via #GrpcClient
The Error itself says that 'only Mutiny service interfaces [...] can be injected via #GrpcClient'
And now im confused. Am I doing anything basically wrong here or is this a strange behaviour?
Hopefully you have some ideas ;)
The interface
session.proto:
syntax = "proto3";
option java_multiple_files = true;
option java_package = "de.ilem0n";
option java_outer_classname = "SessionProto";
package session;
service SessionServiceInterface {
rpc getSessionInfo(SessionRequest) returns (SessionInfoReply) {}
rpc createSession(SessionRequest) returns (SessionInfoReply) {}
}
message SessionRequest {
string sessionId = 1;
}
message SessionInfoReply {
bool isHealthy = 1;
string errorMessage = 2;
string sessionId = 3;
string dnsName = 4;
string ipAddress = 5;
}
SessionService.java:
#GrpcService
public class SessionService implements SessionServiceInterface {
#Inject KubernetesClient k8s;
#Inject SessionBootstrapper sessionBootstrapper;
#Override
public Uni<SessionInfoReply> getSessionInfo(SessionRequest request) {
/* ... boring implementation detail ..*/
}
#Override
public Uni<SessionInfoReply> createSession(SessionRequest request) {
/* ... boring implementation detail ..*/
}

Answer 1

Pre Quarkus 2.8 you need to copy the proto files into the client module. This is not required anymore in 2.8, as you can indicate in which dependency you may have proto files and Quarkus will automatically generate the code from these files.
