this is your problem:
<echo message="directory::exists('${build.dir}') =
${directory::exists('${build.dir}')}"/>
^^^^^^^^^^^^^^
don't quote variable names inside expressions - they will be treated as literal
strings. Use:
${directory::exists(build.dir)} instead.
The reason you're seeing mixed true and false output is this:
1) test that a directory called ${build.dir} exists ( literally that name -
including the $ and {} - returns false
2) test that a directory called build exists. Returns true.

I'm using nant 0.85 rc3 on an xppro box
I am using a variable to hold the word "build" (which is my build directory)
however, directory::exists seems to be working unexpectedly.
specifically notice that what looks like "exists('build')" seems to return both
true and false.
Am I missing something obvious?
Thanks
Malcolm
Here's my script foo
<target name="foo">
<property name="build.dir" value="build" />
<echo message="build.dir = '${build.dir}'"/>
<echo message="directory::exists('${build.dir}') =
${directory::exists('${build.dir}')}"/>
<echo message="directory::exists('bin') = ${directory::exists('bin')}"/>
<echo message="directory::exists('build') =
${directory::exists('build')}"/>
<echo message="attempting to delete build dir"/>
<delete dir="${build.dir}" if="${directory::exists('${build.dir}')}"/>
<echo message="directory::exists('build') =
${directory::exists('build')}"/>
</target>
now here's my results
