Passing version number to install ant task

[Bhatia, Naresh \(IS Consultant\)]

I am using Antlib for Maven 2.0 to install bunch of jar files to my
local maven repository. Is there any way to specify the version number
of these jars in my ant task instead of the pom files? The reason I ask
is that the version nuber is available in my ant script at the time of a
build, whereas it is not convenient (or elegant) to change the version
numbers in each one of the POM files during the build.

Here's a sample of how I am invoking the ant task to install a jar:

    <artifact:install file="${lib.dir}/entities-${build.version}.jar"
pomRefId="entities.pom"/>

What I would really like is

    <artifact:install file="${lib.dir}/entities-${build.version}.jar"
pomRefId="entities.pom" version="${build.version}"/>

Thanks.
