[news.eclipse.newcomer] ANT_HOME variable

[pickgr@xxxxxxxxx (Garret Pick)]

I'm wondering if it's possible to use an environmental variable for 
ant_home in the external tool launch configuration instead of an absolute 
path.  Even a path relative to the workspace location would work for me.

In my *.launch file, I've tried replacing %%% below:

<listEntry value="&lt;?xml version=&quot;1.0&quot; 
encoding=&quot;UTF-8&quot;?&gt;&#10;&lt;runtimeClasspathEntry 
id=&quot;org.eclipse.ant.ui.classpathentry.antH
ome&quot;&gt;&#10;&lt;memento 
antHome=&quot;%%%&quot;/&gt;&#10;&lt;/runtimeClasspathEntry&gt;&#10;"/>

with several things like ${workspace_loc:foo} and ${env_var:ANT_HOME} but 
it doesn't seem to work.

thanks,
Garret
