メソッドの詳細

upToDateWhen

void upToDateWhen(Closure upToDateClosure)

Adds a predicate to determine whether the outputs of this task are up-to-date. The given closure is executed at task execution time. The closure is passed the task as a parameter. If the closure returns false, the task outputs are considered out-of-date and the task will be executed.

You can add multiple such predicates. The task outputs are considered out-of-date when any predicate returns false.

パラメータ:

upToDateClosure - The closure to use to determine whether the task outputs are up-to-date.

upToDateWhen

void upToDateWhen(Spec<? super Task> upToDateSpec)

Adds a predicate to determine whether the outputs of this task are up-to-date. The given spec is evaluated at task execution time. If the spec returns false, the task outputs are considered out-of-date and the task will be executed.

You can add multiple such predicates. The task outputs are considered out-of-date when any predicate returns false.

パラメータ:

upToDateSpec - The spec to use to determine whether the task outputs are up-to-date.

getHasOutput

boolean getHasOutput()

Returns true if this task has declared any outputs. Note that a task may be able to produce output files and still have an empty set of output files.

戻り値:

true if this task has declared any outputs, otherwise false.

getFiles

FileCollection getFiles()

Returns the output files of this task.

戻り値:

The output files. Returns an empty collection if this task has no output files.

files

TaskOutputs files(Object... paths)

Registers some output files for this task.

パラメータ:

paths - The output files. The given paths are evaluated as per Project.files(Object...).

戻り値:

this

file

TaskOutputs file(Object path)

Registers some output file for this task.

パラメータ:

path - The output file. The given path is evaluated as per Project.file(Object).

戻り値:

this

dir

TaskOutputs dir(Object path)

Registers an output directory for this task.

パラメータ:

path - The output directory. The given path is evaluated as per Project.file(Object).

戻り値:

this
