Hello Jacob,
I am not quite sure I understand what do you mean.

Generally, ant-contrib[1] provides looping tasks like
<for> and <foreach>.

What does "a while before" means? If you read the
value of the property from a kind of "asynchronous"
source, you may find useful <sleep>[2] task. Using
<sleep> you can pause your build process for
arbitrarily long time.

Well, after all you can always code a task, or a
script that implements a while loop until the property
is set (not tested, written only by memories):
<scriptdef name="checkProp" language="javascript">
<attribute name="property"/>
<![CDATA[
prop = attributes.get("property");
while (project.getProperty(prop) == null)
{
//keep going
}
//here the property must be set
]]>
</scriptdef>
