No, this is not an Ant script but this snippet can be
used in a <scriptdef>:
<project>
    <scriptdef name="isEmpty" language="javascript">
        <attribute name="dir"/>
        <attribute name="property"/>
        <![CDATA[
            importPackage(java.io);
            file = new File(attributes.get("dir"));
            if(file.isDirectory() &&
(file.list()).length == 0) {
               
project.setNewProperty(attributes.get("property"),
"true");
            }
        ]]>
    </scriptdef>
    <mkdir dir="empty"/>
    <mkdir dir="notempty"/>
    <touch file="notempty/file.txt"/>
    <isEmpty dir="empty" property="empty.empty"/>
    <echo>$${empty.empty} = ${empty.empty}</echo>
    <isEmpty dir="notempty"
property="notempty.empty"/>
    <echo>$${notempty.empty} =
${notempty.empty}</echo>
</project>
