public BZip2()
```
- Method Detail
  - 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.
