Exporting properties and references from a sub-project to its parent
project
This is something I struggled with in NetBeans-generated Java
projects. I wanted to permit build scripts to call dependencies
recursively without reentering any dependencies during a single build
(and maintaining locality of information: a script knows only about
its own direct dependencies). The natural idea is to just set a
property mentioning ${basedir} when building one project and exit
early if it is already set, but this does not work since properties
set in a child cannot be propagated to the parent. The ugly workaround
I found was to create a properties file in a build dir when building
the topmost project, passing its location to children, and loading and
saving it from each build. Obviously this involves otherwise
unnecessary file I/O and is very hard to follow, especially
considering that it is tricky to load properties in an isolated
namespace in Ant, and "if (...) return;" is impossible from the
dependency so a subbuild can be skipped only from the depending script.

The lesson I draw is that Ant without <script> is ill suited to even
moderately complex builds.
Or at the very least Ant Contrib (http://ant-contrib.sourceforge.net/)...
