Move the available task to a target get_jar depends upon, something like
<target name="check_log4j">
<antcall target="get_jar">
<param name="jar" value="${log4j.jar}" />
....
</antcall>
</target>
<target name="check">
<available file="${jar}" property="present "/>
<echo message="${jar} present: ${present}" />
</target>
<target name="get_jar" unless="present" depends="check">
.....
</target>
