Description

I use the 'Retrieve after resolve' feature in order to populate the directory web/WEB-INF/lib
in my project using pattern 'web/WEB-INF/lib/[artifact]-[revision].[ext]'.

This directory is used by the servlet engine in order to load librairies, but the directory can
contain multiple artifact of the same module (mylib-1.0.jar and mylib-1.1.jar) or old dependencies
if you update your ivy.xml and then resolve again.

I know that removing files based on a pattern is dangerous and not trivial.
Removing files below the longest path without '[' may be a good alternative
(with an optional check box "Clean directory").

Another solution is to keep the previous retrieved artifacts and removing them if still
present just before the new retrieve.
