# App Identity sample for Google App Engine
2+
This sample demonstrates how to use the App Identity APIs on Google App Engine
3+
4+
## Running locally
5+
This example uses the
6+
[Maven gcloud plugin](https://cloud.google.com/appengine/docs/java/managed-vms/maven).
7+
To run this sample locally:
8+
9+
$ mvn gcloud:run
10+
11+
## Deploying
12+
In the following command, replace YOUR-PROJECT-ID with your
13+
[Google Cloud Project ID](https://developers.google.com/console/help/new/#projectnumber).
14+
15+
$ mvn gcloud:deploy -Dgcloud.gcloud_project=YOUR-PROJECT-ID
16+
17+
## Setup
18+
To save your project settings so that you don't need to enter the
19+
`-Dgcloud.gcloud_project=YOUR-CLOUD-PROJECT-ID` parameters, you can:
20+
21+
1. Update the <application> tag in src/main/webapp/WEB-INF/appengine-web.xml
22+
with your project name.
23+
24+
You will now be able to run
25+
26+
$ mvn gcloud:deploy
27+
28+
without the need for any additional parameters.
