/**
 * Declares that the changes for an input file or output property should not be tracked by Gradle.
 *
 * <p>Untracked inputs or outputs can be considered as locations Gradle is not supposed to understand.
 * Gradle may not understand the locations for different reasons, for example:
 * <ul>
 *     <li>The location contains unreadable files like pipes where Gradle cannot track the content.</li>
 *     <li>Another tool like Git already takes care of keeping the state, so it doesn't make sense for Gradle to do additional bookkeeping.</li>
 * </ul>
 * </p>
 *
 * <p>If a task has any untracked properties, then Gradle does not do any optimizations for running the task.
 * For example such a task will always be out of date and never from the build cache.</p>
 *
 * <p>{@link org.gradle.work.InputChanges} cannot be used for a task which has untracked properties,
 * since incremental tasks need to understand their inputs and outputs for them to be correct.</p>
 *
 * <p>This annotation can be attached to properties annotated with {@link InputFile}, {@link InputFiles}, {@link InputDirectory},
 * {@link OutputFile}, {@link OutputFiles}, {@link OutputDirectory}, or {@link OutputDirectories}.</p>
