  - ### getSource

    @InputFiles @SkipWhenEmpty @IgnoreEmptyDirectories @PathSensitive(ABSOLUTE) public FileTree getSource()
    Returns the source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

    The `PathSensitivity` for the sources is configured to be `PathSensitivity.ABSOLUTE`. If your sources are less strict, please change it accordingly by overriding this method in your subclass.

    public void setSource(FileTree source)
    Sets the source for this task.
    Parameters:
      `source` - The source.
    Since:
      4.0

  - ### setSource

    public void setSource(Object source)
    Sets the source for this task. The given source object is evaluated as per `Project.files(Object...)`.
    Parameters:
      `source` - The source.

  - ### source

    public SourceTask source(@Nullable Object... sources)
    Adds some source to this task. The given source objects will be evaluated as per `Project.files(Object...)`.
    Parameters:
      `sources` - The source to add
    Returns:
      this

  - ### include

    public SourceTask include(String... includes)
    Adds an Ant style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call.

If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
    Specified by:
      `include` in interface `PatternFilterable`
    Parameters:
      `includes` - a Iterable providing more include patterns
    Returns:
      this
    See Also:
      - Pattern Format

  - ### include

    public SourceTask include(Spec<FileTreeElement> includeSpec)
    Adds an include spec. This method may be called multiple times to append new specs. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.

If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
    Specified by:
      `include` in interface `PatternFilterable`
