Getting started with Google App Engine

IntelliJ IDEA lets you create Google App Engine projects and upload your applications to Google infrastructure.

Make sure that you installed and enabled the Google App Engine plugin. For more information, see Enable cloud support.

1. If no project is currently open in IntelliJ IDEA, click Create New Project on the Welcome screen. Otherwise, select File | New | Project.

   As a result, the New Project wizard opens.

2. In the left-hand pane, select Java.

3. In the right-hand pane, select your project SDK.

4. Under Additional Libraries and Frameworks select Google App Engine.

   

   Note that the Web Application option will be selected automatically.
   

5. In the Google App Engine SDK field, select the SDK you want to use. If the list is empty click Download link to download the latest Google App Engine SDK. If the field doesn't contain the SDK that you want, click and select the installation folder of the required Google App Engine SDK in the dialog that opens.

6. Click Next.

7. On the next page of the wizard, specify the name and location settings.

   Click Finish.

   IntelliJ IDEA creates an empty Google App Engine project. Depending on the selected persistence type, IntelliJ IDEA generates persistence.xml for JPA or jdoconfig.xml for JDO and takes the required libraries from the App Engine SDK.
