Using ANT can you make a copy of the build Log
Accepted answer
I am not sure what you have tried and if there is a problem. But I typed "ant copy file" into a search engine and got http://ant.apache.org/manual/Tasks/copy.html as the first hit. Have you tried that?

The timestamp in the build log file name is not published as an Ant property, so you'll likely need to use the Ant copy task as Ralph suggests, with a wildcard to match build-*.log.
Note that older files may still be around, e.g. if JBE wasn't able to complete the build and publish the log file normally (e.g. if JBE was killed / crashed, or RTC server was unreachable).
