### setSrc

    public void setSrc(java.lang.String src)

  Deprecated. setSrc(String) is deprecated and is replaced with setSrc(File) to make Ant's Introspection mechanism do the work and also to encapsulate operations on the type in its own class.

### setDest

    public void setDest(java.lang.String dest)

  Deprecated. setDest(String) is deprecated and is replaced with setDest(File) to make Ant's Introspection mechanism do the work and also to encapsulate operations on the type in its own class.

  Description copied from class: `Task`
  Called by the project to let the task do its work. This method may be called more than once, if the task is invoked more than once. For example, if target1 and target2 both depend on target3, then running "ant target1 target2" will run all tasks in target3 twice.

    `BuildException` - if something goes wrong with the build

### getDefaultExtension
