This is the example code for the Eclipse RCP commercial training from vogella GmbH. It is also used in the Eclipse Rich Client Platform book.
Clone the project and import all projects except the projects with nattable into the Eclipse IDE.
Then open the target-platform.target file of the target-platform project and set this target definition as target platform for your workspace.
When the compile errors are gone the target platform has been properly set and the product located in the com.vogella.task.product project can be run.
