I ran across a build that uses Get to update to the latest builds of jars.
it is in a target
<target name="get-deps" unless="noget" depends="init">
then you set up
<get dest="${libdir}/commons-io-1.4-SNAPSHOT.jar"
usetimestamp="true" ignoreerrors="true"
src="
http://repo1.maven.org/maven/commons-io/jars/commons-io-1.4-SNAPSHOT.jar">
</get>
so maybe have a build.xml for testing if the new releases.
if anyone is interested, I am making such a build.xml.
I am sure there are things to figure out like cleaning out all previous
jars, then putting them back after the test.
