The Depend sometimes throws a NPE.  Bug exists in 1.4, 1.4.1b1 and current CVS.

Deleting the dependencies.txt file typically solves the problem. 

    <target name="web:compile"
            depends="web:libs">
        <depend srcdir="web/java"
                destdir="build/web/app/WEB-INF/classes"
                cache="build/web/depcache">
            <classpath refid="web:compile.classpath" />
        </depend>
        ...
