This procedure installs the Google Plugin for Eclipse and the Google App Engine SDK. Start Eclipse, then select Help > Install New Software… In the dialog that appears, enter the following update site URL into the “Work with” text box:
http://dl.google.com/eclipse/plugin/4.3
After entering the update site URL for your version of Eclipse (in my case, that is Eclipse Kepler 4.3), click on the “Add” button.
Give the update repository a name.
Select the components you want to install.
Confirm the installation details.
Accept the license agreement.
And finally restart Eclipse.
You're done! Now you are ready to build Google App Engine web applications with Eclipse. In case you need more information, have a look at the installation instructions on Google.
You might run into the following problem and error message when trying to deploy an application to Google App Engine.
Unable to update app: Cannot get the System Java Compiler. Please use a JDK, not a JRE.
This problem occurs if Eclipse is executed with a JRE. The deployment plugin will then use this JRE instead of the JDK when deploying to Google App Engine, even if the preferred Java environment is set to use a JDK. The solution is to start Eclipse with a JDK.
