Go 1.11 はサポートが終了しており、2026 年 1 月 31 日に非推奨になります。非推奨になると、過去に組織のポリシーを使用して以前のランタイムのデプロイを再度有効にしていた場合でも、Go 1.11 アプリケーションをデプロイできなくなります。既存の Go 1.11 アプリケーションは、非推奨日以降も引き続き実行され、トラフィックを受信します。サポートされている最新バージョンの Go に移行することをおすすめします。

In some cases you might need to delete a task that cannot be completed\nsuccessfully, no matter how many times it is retried.\n| This API is supported for first-generation runtimes and can be used when [upgrading to corresponding second-generation runtimes](/appengine/docs/standard/\n| go\n| /services/access). If you are updating to the App Engine Go 1.12+ runtime, refer to the [migration guide](/appengine/migration-center/standard/migrate-to-second-gen/go-differences) to learn about your migration options for legacy bundled services.\n\nDeleting tasks from a queue\n---------------------------\n\n### API\n\nUse [`taskqueue.Delete`](/appengine/docs/legacy/standard/go111/taskqueue/reference#Delete) to delete an individual task:\n\n\u003cbr /\u003e\n\n // Delete an individual task...\n t := &taskqueue.Task{Name: \"foo\"}\n err = taskqueue.Delete(ctx, t, \"queue1\")\n\n### Console\n\n\nTo delete a task from the Google Cloud console:\n\n1. Open the Cloud Tasks page in the console.\n\n [Go to Cloud Tasks](https://console.cloud.google.com/cloudtasks)\n2. Click the name of the queue from which you want to remove the task.\n\n3. Select the task that you want to delete and click **Delete selected tasks**.\n\n4. Click **Delete**.\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nPurging all tasks from a queue\n------------------------------\n\n### API\n\nUse [`taskqueue.Purge`](/appengine/docs/legacy/standard/go111/taskqueue/reference#Purge) to delete all tasks from the specified queue:\n\n\u003cbr /\u003e\n\n // Purge entire queue...\n err := taskqueue.Purge(ctx, \"queue1\")\n\n### Console\n\n\nTo delete a task from the Google Cloud console:\n\n1. Open the Cloud Tasks page in the console.\n\n [Go to Cloud Tasks](https://console.cloud.google.com/cloudtasks)\n2. Click the name of the queue from which you want to remove the task.\n\n3. Select the task that you want to delete and click **Delete all tasks**.\n\n4. Click **Delete**.\n\n\u003cbr /\u003e\n\nAll tasks created before the moment of purging are expunged. Purge operations\ncan take up to one minute to take effect.\n\nIt can take several hours to reclaim the quotas freed up by purging a queue.\n| **Warning:** Do not create new tasks immediately after purging a queue. Wait at least a second. Tasks created in close temporal proximity to a purge call will also be purged.\n\nPausing queues\n--------------\n\nYou can pause a queue by removing its definition from your file\nand then uploading the edited file. Setting any queue's rate to\n0 will also pause the queue.\n\nAny tasks that remain on a paused queue or any new tasks that are added to it\nwill not be processed. You can resume the paused queue by uploading a new\nfile with the queue defined and rate set to a non-zero value.\nPaused queues continue to count as a part of your quota.\n\nYou can also pause a queue from within the\n[Cloud Tasks page in the Google Cloud console](https://console.cloud.google.com/cloudtasks)\n\nDeleting queues\n---------------\n\nIt is a best practice to pause a queue before you delete it:\n\n1. Remove the queue definition from your file.\n\n2. Upload the change to your file.\n\n gcloud app deploy\n\nOnce the queue is removed from your file, use the Google Cloud console to delete it.\n\n1. In the Google Cloud console, select the queue.\n\n [Go to Cloud Tasks](https://console.cloud.google.com/cloudtasks)\n2. Click **Delete queue**.\n\nIf you delete a queue from the Google Cloud console, you must wait 7 days\nbefore recreating with the same name."]]
