How to capture ID and name of current deliverable in Apache Ant build files?

[stefan-jung]

This is related to #4451. I'd like to echo the name and the ID of the deliverable in an Ant script. Is there an undocumented property? I could not find anything in the docs or in the code. I'm looking for this:

Publishing deliverable 67 of 159: NAME OF THE DELIVERABLE [ID OF THE DELIVERABLE]

Current hackish workaround to add an <echo> in the init phase with WARNING level to echo the path of the currently processed map.

<echo level="warning">Publishing map: ${args.input}</echo>
