Gradle enforces isolation of instances of `ComponentMetadataRule`.
This means that all parameters must be `Serializable` or known Gradle types that can be isolated.

In addition, Gradle services can be injected into your `ComponentMetadataRule`.

                implementation 'composite-lib:composite-lib'
            }

            @CacheableRule
            abstract class ChangingAttributeRule implements ComponentMetadataRule {
                final String attrValue
                @Inject ChangingAttributeRule(String attrValue) { this.attrValue = attrValue }
                void execute(ComponentMetadataContext context) {

    // Because this is done directly by the plugin application logic, we can't use a ComponentMetadataRule to exclude it.
