null path references & javac
Another angle on the problem...
I pass the following classpath to the javac task, yet the
dependencies.classpath reference may or may not exist as the reference is
generated by another task which may not set it if no dependencies are
identified.
<classpath id="component.classpath">
<fileset dir="lib" includes="*.jar,*.zip" />
<path refid="dependencies.classpath" />
</classpath>
When the reference isn't set, javac dies. We don't seem to have a concept of
a legitimately null path reference, so I have to resort to a conditional and
two different javac calls. Is there another way around this problem?

Use <path id="dependencies.classpath"/> at the top level and live
with the "Trying to override ..." message when your task sets it to
a different value.

Depends on how dynamic you need the evaluation of
dependencies.classpath's presence to be... would it be
the same for each macro invocation?
