Ah ok, so it's good to use this. With your hint, I found this:
http://lintian.debian.org/tags/debhelper-but-no-misc-depends.html
which makes it mandatory.

That would fit in with my thoughts: javahelper-build- (not ant-build-)
packages declare ${java:Depends}, from the javahelper docs:
jh_depends
----------
`jh_depends` works like `dpkg-shlibdeps`, but for jar
files. For each jar in the package it takes the jars on which it depends
and finds the packages to which they belong. These are included in the
debhelper substvars as ${java:Depends}. The control file can then just
list that variable which is filled in automatically.
=> so this is probably not necessary for "ant packages".
Thank you Ben!
