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).
