Not directly, but why not just make a macro? Like in (NOTE: this example makes
use of ant-contrib, for <var>):
<property name="tmpdir" location="some/where/under/basedir"/>
<var name="value-from-manifest"/>
<macrodef name="read-from-manifest">
<attribute name="jar"/>
<attribute name="attr"/>
<sequential>
<unjar src="@{jar}" dest="${tmpdir}">
<patternset includes="META-INF/MANIFEST.MF"/>
</unjar>
<!--
Then do what's necessary to fill $value-from-manifest
with the value of @attr; the manifest will be in
${tmpdir}/META-INF/MANIFEST.MF
-->
</sequential>
</macrodef>
