Creating Tycho product error: Missing requirement

I'm new to Tycho. I am trying to create a product using Tycho, but every time I run it, I run into the following error:

Cannot resolve project dependencies:

Did you tell Tycho where to look for dependencies? Unlike in Maven, Tycho does not have a default repository where it looks for dependencies. You need to configure this search scope - the so-called target platform - explicitly, e.g. with

<repository>
  <id>eclipse-indigo</id>
  <layout>p2</layout>
  <url>http://download.eclipse.org/releases/indigo</url>
</repository>

More options to configure the target platform can be found here in the documentation.
