/**
 * These keys determine the order in which the {@code ProjectDataService}s are invoked. The order is:
 * <ol>
 * <li>{@link com.android.tools.idea.gradle.service.GradleProjectDataService}</li>
 * <li>{@link com.android.tools.idea.gradle.service.AndroidProjectDataService}</li>
 * <li>{@link com.android.tools.idea.gradle.service.JavaProjectDataService}</li>
 * <li>{@link com.android.tools.idea.gradle.service.ProjectCleanupDataService}</li>
 * </ol>
 * <br/>
 * The reason for following this order is that we need to add the {@code AndroidGradleFacet} to each of the modules. This facet contains the
 * "Gradle path" of each project module. This path is necessary when setting up inter-module dependencies.
