Unable to inject @GrpcClient in quarkus "The following beans match by type, but none have matching qualifiers"

[denysandriyanov]

Describe the bug

I am trying to create gRPC client in Quarkus. Did everything according to the documentation.

Placed proto files in src/main/proto: here is the content of the service file

syntax = "proto3";

package userinfo.grpc;

import "UserInfoRequest.proto";
import "UserInfoResponse.proto";

service UserInfoService {
rpc GetUserInfo (UserInfoRequest) returns (UserInfoResponse);
}
added to gradle following dependency:

implementation 'io.quarkus:quarkus-grpc'
When I built the project I saw my gRPC classes generated in

\build\classes\java\quarkus-generated-sources\grpc\userinfo

Expected behavior

@GrpcClient injected without exceptions

Actual behavior

Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: jakarta.enterprise.inject.spi.DeploymentException: jakarta.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type userinfo.grpc.UserInfoService and qualifiers [@default] - java member: <my_package>.userinfo.grpc.IdentityUserInfoProviderGrpc():userInfoService - declared on CLASS bean [types=[<my_package>.userinfo.UserInfoProvider, java.lang.Object, <my_package>.userinfo.grpc.IdentityUserInfoProviderGrpc], qualifiers=[@default, @Any], target=<my_package>.userinfo.grpc.IdentityUserInfoProviderGrpc] The following beans match by type, but none have matching qualifiers: - Bean [class=userinfo.grpc.UserInfoService, qualifiers=[@Any, @io.quarkus.grpc.GrpcClient("userInfoService")]]

It's the @lombok.AllArgsConstructor annotation that causes the problem. According to the docs it generates an all-args constructor for every field in the class. However, in Quarkus if a bean class declares a single constructor then all the arguments are considered injection points. And you can't inject a grpc client without the @GrpcClient qualifier.

Simply remove the annotation. It's not needed at all.
