For up-to-date checks Gradle relies on tracking the state of the inputs and the outputs of a task.
Gradle used to ignore unreadable files in the input or outputs to support certain use-cases, although it cannot track their state.
Declaring input or output directories on tasks which contain unreadable content has been deprecated and these use-cases are now supported by declaring the task to be untracked.
