I have a ant build file as follows:
<project name="test" basedir=".">
      <property name="lib.dir"           value="/data/java_library/ext"/>
      <path id="project.classpath">
            <fileset dir="${lib.dir}">
                  <include name="**/*.jar"/>
                  <include name="**/*.zip"/>

I would to run something like:

MYCLASSPATH=`ant -q cp`

which should set the environment variable MYCLASSPATH to whatever is defined in the ant build file.

how can I do that?

See below:
<property name="cp" refid="project.classpath" />
<echo message="${cp}" />

It works!
Thanks CEHJ.

If someone is interested, add this to the build.xml
      <property name="cp" refid="project.classpath" />
      <target name="cp" description="Shows the classpath">
            <echo message="${cp}"/>
And then execute:
MYCLASSPATH=`ant -q cp | sed -n -e "s/     \[echo\] //p"`

You might find it more convenient to do
      <property name="cp" refid="project.classpath" />
        <echo message="${cp}" file="cp.txt" />
