<?xml version="1.0"?>

<!-- ===================================================================
     Define a macro to fetch jars from the bedework repository or from
     the generated library in the named project.

     IF a project is named and we cannot locate the named file we try the
     repository.

     For jars fetched from the archive we have a two step process, first check
     that a copy in a local cache is up to date, second copy from the local cache
     into the final destination. This allows the caller to delete and recreate the
     destination, ensuring that jar version changes don't result in multiple
     copies of a jar.

     @param name     Name of the jar e.g. junit
     @param version  optional version for the jar
     @param src      optional url for the get task
     @param lib      optional destination for the get task
     @param libcache optional location of the cache
     @param property optional name of property to hold localtion of resulting jar
     @param project optional project name for local fetch from generated quickstart.
