- ## Method Details

  - ### pack

    protected void pack()
    Compress the zipFile.
    Specified by:
      `pack` in class `Pack`

  - ### supportsNonFileResources

    protected boolean supportsNonFileResources()
    Whether this task can deal with non-file resources.

    This implementation returns true only if this task is <bzip2>. Any subclass of this class that also wants to support non-file resources needs to override this method. We need to do so for backwards compatibility reasons since we can't expect subclasses to support resources.

    Overrides:
      `supportsNonFileResources` in class `Pack`
    Returns:
      true if this task support non file resources.
