=== Fine-grained tracking of Gradle properties as build configuration inputs

Currently, all external sources of Gradle properties (`gradle.properties` in project directories and in the `<<directory_layout.adoc#dir:gradle_user_home,GRADLE_USER_HOME>>`, environment variables and system properties that set properties, and properties specified with

 * <code>rootProject</code> property.  The properties of this scope are readable or writable depending on the presence
 * of the corresponding getter or setter method.</li>
 *
 * <li>The extra properties of the project.  Each project maintains a map of extra properties, which
 * can contain any arbitrary name -&gt; value pair.  Once defined, the properties of this scope are readable and writable.

==== IdeaModule API Cleanup

The deprecated `testSourceDirs` and `testResourceDirs` properties of the `IdeaModule` type have been removed.

On the command line, add this to your Gradle invocation:

[source,properties]
----
-Djavax.xml.accessExternalDTD=http
----

To make this workaround persistent, add the following line to your `gradle.properties`:

[source,properties]
----
systemProp.javax.xml.accessExternalDTD=http
----

			obj, ok := schema.Items.Schema.Properties[k]
			if !ok {
				// we validate that all XListMapKeys are existing properties in ValidateCustomResourceDefinitionOpenAPISchema, so skipping here is ok
				continue
			}

			if isRequired[k] == false && obj.Default == nil {
