The Google Plugin for Eclipse (GPE) is no longer available. This document describes how to migrate a project that uses GPE to Cloud Tools for Eclipse.
App Engine Standard
Cloud Tools for Eclipse supports development for the App Engine environment. To migrate your existing GPE project to Cloud Tools for Eclipse:
Ensure you're running Eclipse IDE for Java EE Developers, version 4.8 to 4.21.
Install Cloud Tools for Eclipse. This process uninstalls GPE.
Open the Project Explorer in Eclipse.
Right click the project you want to convert and select Configure > Convert to App Engine Project.
You can edit your Apps Script projects directly in your web browser using the Google Drive script editor.
All of your Apps Script projects are already available in Google Drive, without additional export or conversion.
Install the GWT Eclipse plugin.
You may see build errors in your GWT projects. To resolve them:
Select the Project in the Project Explorer.
Open the context menu.
Select Configure > Enable GWT SDM builder.
App Engine + GWT
App Engine code runs on the server, and GWT code runs on the client, though it's compiled and served from the server. Ideally you should divide these into separate projects: an App Engine Eclipse project and a GWT Eclipse project.
Android Studio is the official IDE for Android development.
You can convert your existing Eclipse Android projects into Android Studio projects with Gradle-based build files using the procedures to migrate from Eclipse.
No IDE, Eclipse included, currently provides integrated support for Endpoints v2. You can work with Endpoints v2 projects in Eclipse, as you would with any other Java project. However, there are no Endpoints specific code inspections, code generators, new project wizards, editors, or deployment tools.
If you wish to continue using Endpoints v1, you can likewise import your backend project into Eclipse as you would any other Java project. The simplest approach for working with Endpoints v1 without GPE is to leverage the com.google.appengine:appengine-maven-plugin and the Eclipse m2e integration.
If your project is not already built with maven, you need to add a
If necessary, install the m2e plugin.
Select the project in the Project Explorer.
From the context menu, select Configure > Convert to Maven Project. This conversion adds a
pom.xmlfile to the project and sets the project to use the Maven builder.
Add the following
dependenciesto that pom.xml:
<dependencies> <dependency> <groupId>com.google.appengine</groupId> <artifactId>appengine-endpoints</artifactId> <version>1.9.73</version> </dependency> <dependency> <groupId>org.eclipse.persistence</groupId> <artifactId>javax.persistence</artifactId> <version>2.1.0</version> </dependency> <dependency> <groupId>javax.inject</groupId> <artifactId>javax.inject</artifactId> <version>1</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>com.google.code.findbugs</groupId> <artifactId>jsr305</artifactId> <version>3.0.2</version> </dependency> <dependency> <groupId>com.google.appengine.orm</groupId> <artifactId>datanucleus-appengine</artifactId> <version>2.1.2</version> </dependency> </dependencies>
If your application depends on other libraries, add those dependencies too.
Add this plugin to the
<plugin> <groupId>com.google.cloud.tools</groupId> <artifactId>endpoints-framework-maven-plugin</artifactId> <version>1.0.0</version> </plugin>
pom.xmlis set up, use the
endpoints-framework:discoveryDocsgoal to generate discovery docs:
$ mvn endpoints-framework:discoveryDocs
endpoints-framework:clientLibsgoal to generate client libraries:
$ mvn endpoints-framework:clientLibs
You can map these goals to Eclipse Maven Build run configurations for easy access from the Run menu.
DataNucleus (JPA & JDO)
Cloud Tools for Eclipse does not auto enhance entity classes.
You can use Maven for this functionality.
The development workflows in Cloud Tools for Eclipse support Objectify 5.x with no changes.
If you wish, you can migrate to Objectify 6.0. This migration requires updates
to your project code. Local development with Objectify 6.0 also requires the
Datastore emulator (
gcloud beta emulators datastore), which
must be launched outside of Eclipse and requires some additional configuration
for your launch.
Refer to the Objectify documentation for more information.
Now that you have successfully migrated your project to Cloud Tools for Eclipse, learn more about the available tools and resources.
