public class CloudTasksClient implements BackgroundResource
Service Description: Cloud Tasks allows developers to manage the execution of background work in their applications.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:
try (CloudTasksClient cloudTasksClient = CloudTasksClient.create()) {
QueueName name = QueueName.of("[PROJECT]", "[LOCATION]", "[QUEUE]");
Queue response = cloudTasksClient.getQueue(name);
}
Note: close() needs to be called on the CloudTasksClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().
The surface of this class includes several types of Java methods for each of the API's methods:
- A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
- A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
- A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.
See the individual methods for example code.
Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.
This class can be customized by passing in a custom instance of CloudTasksSettings to create(). For example:
To customize credentials:
CloudTasksSettings cloudTasksSettings =
CloudTasksSettings.newBuilder()
.setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
.build();
CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
To customize the endpoint:
CloudTasksSettings cloudTasksSettings =
CloudTasksSettings.newBuilder().setEndpoint(myEndpoint).build();
CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
Please refer to the GitHub repository's samples for more quickstart code snippets.

}
Name | Description |
parent | QueueName Required. The queue name. For example:
The queue must already exist. |
task | Task Required. The task to add. Task names have the following format:
If schedule_time is not set or is in the past then Cloud Tasks will set it to the current time. Task De-duplication: Explicitly specifying a task ID enables task de-duplication. If a task's ID is identical to that of an existing task or a task that was deleted or executed recently then the call will fail with ALREADY_EXISTS. If the task's queue was created using Cloud Tasks, then another task with the same name can't be created for ~1hour after the original task was deleted or executed. If the task's queue was created using queue.yaml or queue.xml, then another task with the same name can't be created for ~9days after the original task was deleted or executed. Because there is an extra lookup cost to identify duplicate task names, these CreateTask calls have significantly increased latency. Using hashed strings for the task id or for the prefix of the task id is recommended. Choosing task ids that are sequential or have sequential prefixes, for example using a timestamp, causes an increase in latency and error rates in all task commands. The infrastructure relies on an approximately uniform distribution of task ids to store and serve tasks efficiently. |

runTask(RunTaskRequest request)
public final Task runTask(RunTaskRequest request)
Forces a task to run now.
When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its RateLimits or is PAUSED.
This command is meant to be used for manual debugging. For example, RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now.
The dispatched task is returned. That is, the task that is returned contains the status after the task is dispatched but before the task is received by its target.
If Cloud Tasks receives a successful response from the task's target, then the task will be deleted; otherwise the task's schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue's RetryConfig.
RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed.
Sample code:
