# Pull Task Queue sample for Google App Engine | ||
|
||
This sample demonstrates how to use [pull task queues][appid] on [Google App | ||
Engine][ae-docs]. | ||
|
||
[appid]: https://cloud.google.com/appengine/docs/java/taskqueue/overview-pull | ||
[ae-docs]: https://cloud.google.com/appengine/docs/java/ | ||
|
||
## Running locally | ||
This example uses the | ||
[Maven gcloud plugin](https://cloud.google.com/appengine/docs/java/managed-vms/maven). | ||
To run this sample locally: | ||
|
||
$ mvn appengine:devserver | ||
|
||
## Deploying | ||
In the following command, replace YOUR-PROJECT-ID with your | ||
[Google Cloud Project ID](https://developers.google.com/console/help/new/#projectnumber). | ||
|
||
$ mvn appengine:update -Dappengine.appId=YOUR-PROJECT-ID -Dappengine.version=SOME-VERSION | ||
|
||
## Setup | ||
To save your project settings so that you don't need to enter the | ||
parameters, you can: | ||
|
||
1. Update the <application> tag in src/main/webapp/WEB-INF/appengine-web.xml | ||
with your project name. | ||
|
||
2. Update the <version> tag in src/main/webapp/WEB-INF/appengine-web.xml | ||
with a valid version number. | ||
|
||
|
||
You will now be able to run | ||
|
||
$ mvn appengine:update | ||
|
||
without the need for any additional parameters. |
