Method Detail

getUpToDateSpec

public Spec<? super TaskInternal> getUpToDateSpec()

Specified by:

getUpToDateSpec in interface TaskOutputsInternal

upToDateWhen

public void upToDateWhen(Closure upToDateClosure)

Description copied from interface: TaskOutputs

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 If the closure returns false, the task outputs are considered out-of-date and the task will be executed.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 The task outputs are considered out-of-date when any predicate returns false.

Specified by:

upToDateWhen in interface TaskOutputs

Parameters:

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

upToDateWhen

public void upToDateWhen(Spec<? super Task> upToDateSpec)

Description copied from interface: TaskOutputs

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 If the spec returns false, the task outputs are considered out-of-date and the task will be executed.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 The task outputs are considered out-of-date when any predicate returns false.

Specified by:

upToDateWhen in interface TaskOutputs

Parameters:

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

getHasOutput

public boolean getHasOutput()

Description copied from interface: TaskOutputs

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.

Specified by:

getHasOutput in interface TaskOutputs

Returns:

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

getFiles

public FileCollection getFiles()

Description copied from interface: TaskOutputs

Returns the output files of this task.

Specified by:

getFiles in interface TaskOutputs

Returns:

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

files

public TaskOutputs files(Object... paths)

Description copied from interface: TaskOutputs

Registers some output files for this task.

Specified by:

files in interface TaskOutputs

Parameters:

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

Returns:

this

file

public TaskOutputs file(Object path)

Description copied from interface: TaskOutputs

Registers some output file for this task.

Specified by:

file in interface TaskOutputs

Parameters:

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

Returns:

this

dir

public TaskOutputs dir(Object path)

Description copied from interface: TaskOutputs

Registers an output directory for this task.

Specified by:

dir in interface TaskOutputs

Parameters:

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

Returns:

this

getPreviousFiles

public FileCollection getPreviousFiles()

Specified by:

getPreviousFiles in interface TaskOutputsInternal

setHistory

public void setHistory(TaskExecutionHistory history)

Specified by:

setHistory in interface TaskOutputsInternal
