I previously added it to the project's classpath and the error wasn't being resolved so I assumed it wasn't the correct fix. Now I tried adding it to the module path and the error was resolved.

@hjohn Add


	<classpathentry kind="lib" path="../../../build/libs/swt-debug.jar">
		<attributes>
			<attribute name="module" value="true"/>
		</attributes>
	</classpathentry>

to the .classpath file.

I didn't explain this well. There are 3 projects under apps/samples that have a `build.gradle` file with the `application` plugin: Ensemble8, 3DViewer and Modena. This implies that these can be run with Gradle. However, doing so causes the error I posted. The error message is correct in that these 3 projects are not defined in `settings.gradle`, but then why are they Gradle projects?
