Google Cloud Tasks integration

[kamal-j]

Describe the bug

I'm trying to create a quarkus app that creates tasks in Google Cloud Tasks. I'm using the Google Cloud Java Client Library. I'm unable to build my app after integrating the sdk.

This is my quarkus app code :

package org.acme;

import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

import com.google.cloud.tasks.v2.*;
import com.google.protobuf.ByteString;

@Path("/create-task")
public class GreetingResource {

    @Inject
    CloudTasksClient cloudTasksClient;

    @GET
    public String createTask() throws Exception {
        QueueName queueName = QueueName.of("project-id", "location-id", "queue-id");
        Task task = Task.newBuilder()
                .setHttpRequest(
                        HttpRequest.newBuilder()
                                .setUrl("https://task-handler-service.com/handle-task")
                                .setHttpMethod(HttpMethod.POST)
                                .setBody(ByteString.copyFromUtf8("{\"message\":\"test task\",\"reschedule\":true}"))
                                .build())
                .build();
        cloudTasksClient.createTask(queueName, task);
        return "Task created!";
    }
}

I'm getting the following error when building the app :

@kamal-j Google Cloud official clients are not exposed as beans in the libraries. If you want to use them in CDI you need to create a producer method, something like this:

@Singleton
public CloudTasksClient cloudTaskClient() {
    return CloudTasksClient.create();
}

But there is an open issue regarding that in the Quarkiverse repository, where such producer could be added in the future: quarkiverse/quarkus-google-cloud-services#300
