Subject Re: [ANN] Apache Maven Assembly Plugin 2.5.4 Released
Date Mon, 27 Apr 2015 19:00:29 GMT
I divides the zip into N streams where N=number of cpu cores.  Subsequently
files are submitted round-robin to each stream (it's actually fork-join
with work-stealing on java7). Each stream is written to memory with an
offload to disk if it grows too large.  When all streams are done they are
merged back into a single well formed zip file.

This is totally zero-config and cannot be disabled :) Any users of
plexus-archiver can get this feature by simply upgrading to version 2.10
(and plexus-io 2.5). This includes war and jar plugin too.
