Automated replacement of BUILD_LABEL in web.xml <description> with Ant. For JAR’s the replacement is commented out, but can be any file
<replace file="${webapp.dir}/WEB-INF/web.xml" token="BUILD_LABEL" value="Ant-${DSTAMP}-${TSTAMP}" />
<war destfile="${jar.dir}/${ant.project.name}.war" webxml="${webapp.dir}/WEB-INF/web.xml" compress="true">
Most importantly, you will want to have this token in the web.xml file for replacement, the description line is best used for this as such:
<description>ExampleWAR [BUILD_LABEL]</description>
during the build, that value would be replaced to something like:
<description>ExampleWAR [Ant-20141015-1700]</description>
