parameterise overwrite of web.xml in war:war-resources

We have a plugin that modifies the web.xml, as an optimisation we don't have to perform this modification on every build. However, the war:war-resources forces the copy of the web.xml file, so our plugin has to modify the web.xml every time.

<util:available file="${maven.war.webxml}">
<ant:copy file="${maven.war.webxml}"
tofile="${webapp.build.webinf}/web.xml"
overwrite="true" />
</util:available>

how about parameterise? with default true.

<util:available file="${maven.war.webxml}">
<ant:copy file="${maven.war.webxml}"
tofile="${webapp.build.webinf}/web.xml"
overwrite="${war.web.xml.overwrite}" />
</util:available>

I can make patches if needed. nathan@codeczar.com
