You can try replace the first line to

Thanks Vincent. I've tried your suggestion and the explanation seems
fairly simple. "$.." is simply a string, nothing more.
Here's my understanding:
<property name="projects.dir" value="$aaa" />
<echo message="${projects.dir}"/>
[echo] $aaa
So "$aaa" or "$.." are just string values?
<echo message="${projects.dir}\AntLog.log"/>
[echo] $aaa\AntLog.log
A simple string value would also explain this.
<dirname property="projects.dirname" file="${projects.dir}"/>
<echo message="${projects.dirname}"/>
[echo] c:\_Projects
Ant is assuming that "$aaa" is a filename and giving me the current
directory.
<dirname property="logfiledirname" file="${projects.dir}\AntLog.log"/>
<echo message="${logfiledirname}"/>
[echo] c:\_Projects\$aaa
Here Ant assumes that I'm specifying [CurrrentDirectory]\$aaa\AntLog.log
and returns the file's directory path.
Seems pretty straightforward. Let me know if any of this is wrong.
Now I'll go back and look at the file where I first found $.., and see
if I can figure out what they were doing. :-)
Thanks again!

Hi All,
I ran across "$.." in an Ant file and am trying to understand what it
does. Can't find any documentation. So basic as to not require
explanation?
When I run a C:\Projects\build.xml file with this code in it:
<property name="projects.dir" value="$.." />
<dirname property="projects.dirname" file="${projects.dir}"/>
<dirname property="logfiledirname" file="${projects.dir}\AntLog.log"/>
<echo message="${projects.dir}"/>
<echo message="${projects.dirname}"/>
<echo message="${projects.dir}\AntLog.log"/>
<echo message="${logfiledirname}"/>
I get this:
[echo] $..
[echo] c:\Projects
[echo] $..\AntLog.log
[echo] c:\Projects\$..
The first three echoes would make sense to me if $.. indicated the
current directory, but a single dot does that. What's the difference?
The fourth echo doesn't make sense to me at all...
