Use the `archiveAppendix`, `archiveFileName` , `archiveFile`, `archiveBaseName`, `archiveClassifier`, `destinationDirectory`, `archiveExtension` and `archiveVersion` properties instead.

==== 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 {

        public PropertyMetadata getProperty(String name) {
            return properties.get(name);
        }

        public PropertyMetadata property(String name) {
            PropertyMetadata property = properties.get(name);
            if (property == null) {
                property = new PropertyMetadata(name);
                properties.put(name, property);
            }
            return property;
        }

 * The order of elements in `Iterable` properties marked with either `@OutputFiles` or `@OutputDirectories` now matters. If the order changes, the property is no longer considered up to date.
+
Prefer using separate properties with `@OutputFile`/`@OutputDirectory` annotations or use `Map` properties with `@OutputFiles`/`@OutputDirectories` instead.

The problem is that paths often change, and the more places you need to change them, the more likely you will miss one and break the build.

Where possible, you should use tasks, task properties, and <<properties_providers.adoc#understanding_properties,project properties>> — in that order of preference — to configure file paths.
