Subject: Re: target progress bar

/*

At its most rigorous, predicting how long something will take to 
complete requires a solution to the halting problem: a way to predict 
when/whether something will terminate.

However, remembering how long something took last time is a good metric,

and is generally what things like grid workload schedulers do. If you 
submit a job "to the grid", it remembers how long this took last time 
and uses that as a metric of what is likely to be needed.

For ant you could have some profile listener that knows how long 
specific targets/tasks took, and the next run, moves the progress
forwards.

OK, that might be possible, f.e. with a tool like

https://antutility.dev.java.net/ 

a BuildMetricListener.
