How to specify directory or file glob as javac classpath value with Apache Ant?

Question

Is there a way to set the value of the javac classpath property in Apache Ant (v1.9.6) so that I don't have to literally specify all the jars that I want to include e.g. a directory or file glob.

So, if I have something like:

<javac classpath="./lib/one.jar":./lib/two.jar:./lib/three.jar..."

...is there anyway to just specify my ./lib directory once, like the way you can do when you run a java application like:

java -cp ./lib/'*'

I've tried that, and just using ./lib, or./lib/* or ./lib/*.jar but they don't work.

And another solution using a reusable classpath reference:

<path id="compile.path">
  <fileset dir="lib" includes="*.jar"/>
</path>

<javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false" debug="true" classpathref="compile.path"/>

<junit printsummary="yes" haltonfailure="yes">
  <classpath>
    <path refid="compile.path"/>
    <pathelement path="${classes.dir}"/>
  </classpath>
