Question

我一直在尝试使用快速入门指南让Google Pub / Sub Java库工作。他们都没有像书面那样工作，至少不适合我。我在IntelliJ，Maven框架，OSX，Java 8中工作。

选择this example。我遵循了所有步骤：创建了一个服务帐户作为项目所有者，安装了Gcloud SDK，设置了我的GOOGLE_APPLICATIONS_CREDENTIALS envvar，并发现命令行中的所有东西都是hunky dory：我可以创建主题，发布消息，无论我想要什么。

然后当我尝试运行示例代码时：

import com.google.api.gax.rpc.ApiException;
import com.google.cloud.ServiceOptions;
import com.google.cloud.pubsub.v1.TopicAdminClient;
import com.google.pubsub.v1.ProjectTopicName;

public class CreateTopicExample {

  /**
   * Create a topic.
   *
   * @param args topicId
   * @throws Exception exception thrown if operation is unsuccessful
   */
  public static void main(String... args) throws Exception {

    // Your Google Cloud Platform project ID
    String projectId = ServiceOptions.getDefaultProjectId();

    // Your topic ID, eg. "my-topic"
    String topicId = args[0];

    // Create a new topic
    ProjectTopicName topic = ProjectTopicName.of(projectId, topicId);
    try (TopicAdminClient topicAdminClient = TopicAdminClient.create()) {
      topicAdminClient.createTopic(topic);
    } catch (ApiException e) {
      // example : code = ALREADY_EXISTS(409) implies topic already exists
      System.out.print(e.getStatusCode().getCode());
      System.out.print(e.isRetryable());
    }

    System.out.printf("Topic %s:%s created.\n", topic.getProject(), topic.getTopic());
  }
}

抛出ApiException PERMISSION_DENIED。完整的堆栈跟踪：

调试器告诉我为该服务帐户设置了正确的默认项目projectId，因此服务帐户已连接。而且，正如我所说的，我从控制台验证了权限实际上已设置为该服务帐户的Project：Owner。那么......为什么许可被拒绝了？

提前感谢您代表我阅读粗糙的堆栈跟踪。

由于你在运行gcloud没有问题，这一定是IntelliJ的一个问题。您应该检查是否需要通过shell启动IntelliJ（如this文章中所述），或者按照here所述在IntelliJ中设置GOOGLE_APPLICATIONS_CREDENTIALS变量。

项目所有者帐户
