==== IdeaModule API Cleanup

The deprecated `testSourceDirs` and `testResourceDirs` properties of the `IdeaModule` type have been removed.
This affects the `org.gradle.plugins.ide.idea.model.IdeaModule` type, not the `org.gradle.tooling.model.idea.IdeaModule` type.
Use the `testSources` and `testResources` properties instead.

 * Gradle 5.0 requires a minimum Tooling API client version of 3.0. Older client libraries can no longer run builds with Gradle 5.0.
 * The IdeaModule Tooling API model element contains methods to retrieve resources and test resources so those elements were removed from the result of `IdeaModule.getSourceDirs()` and `IdeaModule.getTestSourceDirs()`.
