Haven't looked at the build you included later, but just in case it's
a lucky guess, remember that some "conditionals" in Ant only look at
whether a property is set, rather than its actual value (true or
false, 0, or 1, etc...). For example <target name=3D"..." if=3D"foo"/>,
will execute if property "foo" is *set*, to whatever. This is
typically worked around by using <target name=3D"..." depends=3D"test-foo"
if=3D"foo-is-true?"/> with <target name=3D"test-foo"> <condition
property=3D"foo-is-true?"><istrue property=3D"foo"/></condition></target>.
(WARNING: untested code). This works because is target's dependencies
are always evaluated before itself (if these dependencies haven't been
already satisfied/evaluated). Hope this helps. --DD
