To be able to take advantage of the Update Manager functionality and be able to publish upgrades and patches to your product, your product has to be feature-based.
Creating a feature-based product using the product editor is almost the same as a plugin-based product, with the only difference being the settings on the Configuration page.
Using the New Feature... button on the Configuration page of the product editor, create a feature named com.example.feature that contains plug-in com.example.xyz, as described in the Feature section of the guide.
On the Overview page of the feature editor, the feature must declare the com.example.xyz plug-in as its branding plug-in.
Add the org.eclipse.rcp feature to the list of features to be included in your product.
That is it!
Proceed to the Exporting a Product section as you normally would with a plugin-based configuration.
