As a result, Cloud Code disables App Engine by default. To enable App Engine in your IDE, navigate to **Settings** \\\u003e **Google\n| Cloud Code** \\\u003e **App Engine** . Due to the upcoming deprecation of App Engine, we don't recommend creating new App Engine projects. For more information about App Engine deprecations, see [Feature deprecations](/appengine/docs/standard/deprecations). For more information about the runtime support schedule for App Engine, see [Runtime support schedule](/appengine/docs/standard/lifecycle/support-schedule).\n\nBefore you begin\n----------------\n\n- If your project is Maven or Gradle based and uses the older\n App Engine SDK based plugins (e.g.\n `com.google.appengine.appengine-maven-plugin` and\n `com.google.appengine:gradle-appengine-plugin`), you should first migrate to\n the new gcloud CLI based\n [Maven](/appengine/docs/standard/java/tools/migrate-maven)\n and\n [Gradle](/appengine/docs/standard/java/tools/migrate-gradle)\n plugins.\n\n- The new plugin does not support Datanucleus enhancement. If you depend on\n this feature, you will have to manually configure Datanucleus\n ([JDO](/appengine/docs/standard/java/datastore/jdo/overview-dn2),\n [JPA](/appengine/docs/standard/java/datastore/jpa/overview-dn2))\n enhancement for your project to migrate to Cloud Code.\n You should use\n [Objectify](/appengine/docs/legacy/standard/java/datastore#using_objectify_with)\n as your ORM layer when reading/writing to Datastore.\n\nInstall the new plugin\n----------------------\n\nIf you haven't already, install the plugin by doing the following:\n\n- Ensure you have the supported IDE version, JetBrains IDE version 2022.3+ (such as IntelliJ Ultimate/Community, PyCharm Professional/Community, WebStorm, GoLand), on the `PATH` of your machine.\n- Open IntelliJ IDEA (or any supported JetBrains IDE).\n- Open the plugins marketplace window using **File** \\\u003e **Settings** \\\u003e **Plugins** . For Mac OS X, use **IntelliJ IDEA** \\\u003e **Preferences** \\\u003e **Plugins**.\n- Search for the 'Cloud Code' plugin and install it.\n\n You may be prompted to restart your IDE to activate the plugin.\n\nConfigure IntelliJ and your project\n-----------------------------------\n\nAfter installing the plugin, configure IntelliJ and your project to use the new\nplugin as follows:\n\n1. When notified that the new plugin conflicts with the existing\n App Engine integration, click the link in the prompt.\n\n2. In the following Disable Plugin prompt, select 'Disable and Restart' to\n disable the App Engine plugin and restart the IDE for the plugin\n configuration changes to take effect.\n\n3. When notified that your project is in an old format, click the option to\n **Convert** your project to the new format.\n\n4. You should delete your existing App Engine Server and Cloud\n instances and recreate them using the new gcloud CLI.\n\n 1. Navigate to **Settings** \\\u003e **Build, Execution, Deployment** \\\u003e\n **Application Servers**.\n\n 2. Select your **App Engine Dev** instances and click\n **Delete** (-).\n\n 3. Click **Add** (+) and select **Google App Engine Dev Server**.\n\n 4. Navigate to **Settings** \\\u003e **Build, Execution, Deployment** \\\u003e\n **Clouds**.\n\n 5. Select your **Google App Engine** cloud instances and click\n **Delete** (-).\n\n 6. Click **Add** (+) to configure an App Engine cloud deployment\n target.\n\n5. If you have any App Engine local server run configurations, then\n you must update them to use the newly configured Application Server.\n\n6. Navigate to **Tools** \\\u003e **Cloud Code** \\\u003e **App Engine** to see the list of actions\n available to you for running and deploying your application, or view\n [the documentation](/code/docs/intellij/how-to) for more information.\n\n7. For Maven or Gradle-based projects, ensure that you are using the latest\n version of the Gradle and Maven App Engine plugins.\n\nConfiguring IntelliJ-specific projects\n--------------------------------------\n\nFor IntelliJ-specific projects only (i.e., projects that have manually configured\nproject settings with the old App Engine facet and are not synced from\nGradle or Maven), update your App Engine dependencies.\n\nYour App Engine dependencies are still configured as\n'External Libraries' and provided by your old App Engine SDK\ninstallation. If you delete your App EngineSDK installation, your\napplication will not compile.\n\nTo remove this dependency on the old App Engine SDK, configure your\nApp Engine API dependencies using the App Engine Facet\nlibrary import feature as follows:\n\n1. Users of the old plugin's Datanucleus JDO/JPA enhancement feature need to\n port their applications to Maven or Gradle as Datanucleus enhancement is not\n supported by the Cloud Code plugin.\n\n2. From the IntelliJ Project Structure UI, navigate to your App Engine\n Standard module's dependencies tab.\n\n3. Remove all App Engine related libraries.\n\n4. In the same Project Structure UI, navigate to your App Engine\n module's **Google App Engine** facet.\n\n5. In the **Libraries** panel, select the App Engine dependencies you\n are using.\n\n This action will automatically retrieve these dependencies from Maven\n Central and add them to your module classpath.\n6. Run locally and deploy to verify your new configuration is working.\n\n7. At this point, you can safely delete your old App Engine SDK.\n\nGet support\n-----------\n\nTo submit feedback or report an issue in your IntelliJ IDE, go to **Tools** \\\u003e **Cloud Code** \\\u003e **Help / About** \\\u003e **Submit\nfeedback or report an issue** to report an issue on [GitHub](https://github.com/GoogleCloudPlatform/cloud-code-intellij/issues)."]]
