#### setSrc

    public void setSrc(java.io.File src)

The file to expand; required.

Parameters:
  `src` - file to expand

#### setSrcResource

    public void setSrcResource(Resource src)

The resource to expand; required.

Parameters:
  `src` - resource to expand

#### addConfigured

    public void addConfigured(ResourceCollection a)

Set the source Archive resource.

Parameters:
