Hi,

is there a simpler way to create a required folder if it does not
exist already? Using a standard Ant installation (to my understanding,
core tags do not include an <if> tag).

    <target name="checkavailabledirs">
        <available file="${classes}" type="dir" property="classes.present"/>
    </target>

    <target name="createsourcedir" unless="${classes.present}">
        <mkdir dir="${classes}"/>
    </target>

    <target name="init" depends="checkavailabledirs, createsourcedir"/>

    <target name="compile" depends="init">
          ....

That works fine, but boy, is it overcomplicated.
