Method Detail

getHasInputs

boolean getHasInputs()

Returns true if this task has declared the inputs that it consumes.

Returns:

true if this task has declared any inputs.

getFiles

FileCollection getFiles()

Returns the input files of this task.

Returns:

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

files

TaskInputs files(Object... paths)

Registers some input files for this task.

Parameters:

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

Returns:

this

file

TaskInputs file(Object path)

Registers some input file for this task.

Parameters:

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

Returns:

this

dir

TaskInputs dir(Object dirPath)

Registers an input directory hierarchy. All files found under the given directory are treated as input files for this task.

Parameters:

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

Returns:

this

getProperties

Map<String,Object> getProperties()

Returns the set of input properties for this task.

Returns:

The properties.

property

TaskInputs property(String name,
                  Object value)

Registers an input property for this task. This value is persisted when the task executes, and is compared against the property value for later invocations of the task, to determine if the task is up-to-date.

The given value for the property must be Serializable, so that it can be persisted. It should also provide a useful equals() method.

You can specify a closure or Callable as the value of the property. In which case, the closure or Callable is executed to determine the actual property value.

Parameters:

name - The name of the property. Must not be null.

value - The value for the property. Can be null.

properties

TaskInputs properties(Map<String,?> properties)

Registers a set of input properties for this task. See property(String, Object) for details.

Parameters:

properties - The properties.

getHasSourceFiles

boolean getHasSourceFiles()

Returns true if this task has declared that it accepts source files.

Returns:

true if this task has source files, false if not.

getSourceFiles

FileCollection getSourceFiles()

Returns the set of source files for this task. These are the subset of input files which the task actually does work on. A task is skipped if it has declared it accepts source files, and this collection is empty.

Returns:

The set of source files for this task.

source

TaskInputs source(Object... paths)

Registers some source files for this task. Note that source files are also considered input files, so calling this method implies a call to files(Object...).

Parameters:

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

Returns:

this

source

TaskInputs source(Object path)

Registers some source files for this task. Note that source files are also considered input files, so calling this method implies a call to files(Object...).

Parameters:

path - The path. This is evaluated as per Project.files(Object...).

Returns:

this

sourceDir

TaskInputs sourceDir(Object path)

Registers a source directory for this task. All files under this directory are treated as source files for this task. Note that source files are also considered input files, so calling this method implies a call to dir(Object).

Parameters:

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

Returns:

this
