/**
 * Attached to a task to declare that the task should be untracked.
 *
 * If a task is untracked, then Gradle will not try to capture its state.
 * That also means that Gradle does not do any optimizations for running the task.
 * For example, such a task will always be out of date and never stored in or loaded from the build cache.
 *
 * 
There can be different reasons for declaring a task as untracked, for example:
 * 

 *     Some input or output locations contain unreadable files like pipes where Gradle cannot track the content.
 *     The input or output is stored remotely, for example in a database, and its state cannot be tracked.
 *     Another tool like Git already takes care of keeping the state, so it doesn't make sense for Gradle to do additional bookkeeping.
 *     Prevent Gradle from trying to snapshot a potentially large amount of content if an output location is not exclusively owned by the build.
 * 
 *
 * {@link org.gradle.work.InputChanges} cannot be used for untracked tasks,
 * since incremental tasks need to track the state of their inputs and outputs for them to be correct.
 *
