Stephane Nicoll closed MWAR-138.
--------------------------------
Resolution: Won't Fix
Well it may be big but it is an optimisation. If you run mvn package several
times and the different overlays have not changed, it won't unpack them again
(so it's much faster).
> Cleanup of war/work after war overlay
> -------------------------------------
>
> Key: MWAR-138
> URL: http://jira.codehaus.org/browse/MWAR-138
> Project: Maven 2.x War Plugin
> Issue Type: Improvement
> Affects Versions: 2.1-alpha-1
> Reporter: Michele Lorenzini
> Priority: Minor
>
> I'm using war overlay to build a final war application from many other war
> projects which overlays in the final artifact.
> I've noticed the overlay mechanism uses a working dir (target/war/work) where
> all wars are copied before being overlaid on the target war.
> This folder is left there after the build.
> This folder can become a little big after a build, so I think there should be
> a way to handle the cleanup of this working folder after that.
> I think it should be deleted automatically by default after the overlay has
> finished, maybe with an option to disable the cleanup, which can be
> useful if I need to "see" what the plugin is overlaying.
> I know that a mvn clean will also cleanup this, but it will also cleanup the
> final build of the artifact.
> As an example, I have a scenario where a base war project has the most of the
> files used by the final war.
> This is also used by all the war submodules so I can build and run each
> module indipendently, in this way each war output is similar to others in size
> (say around 15MB).
> When I build the final war overlaying all of these wars (producing a final
> war of say 20MB) I have a war/work folder which is 15M x N where N is the
> numbre of submodules (I have a dozen of them at now but can be more in the
> future, coming in a waste of disk space in the target folder after each
> build).
