 * Before task execution ({@link org.gradle.api.internal.tasks.execution.ExecuteTaskBuildOperationType}),
 * the mutations of the task need to be resolved. The mutations of a task are the locations it may modify,
 * e.g. its outputs, destroyables and local state. In order to resolve the mutations, the task input and output
 * properties are detected as well. Since Gradle 7.5, resolving of the mutations happens in a separate node
 * in the execution graph.
