Great example Matt! Just be aware Martin that calling 100 times a target
using <antcall> (that's what <foreach> does internally) is very memory
intensive (basically, it duplicates the Ant Project for each <antcall>), and
a few people have run into trouble with OutOfMemoryErrors... Forking tasks
like <javac> is usually a good idea in this case, as <javac> is notorious
for not releasing resources properly otherwise. Just a heads up! --DD
PS: Scan the mailing lists for recent posts about
'foreach' and 'outofmemory'.

Subject: RE: calling tasks per directory?
Since I was already working on it, here is a sample...
I used Erik's suggestion from earlier today about
directly making a path into a property without using
<pathconvert>, and just specified the current
path.separator to <foreach>:
<project name="iteratedirs" default="default"
basedir=".">
<taskdef
resource="net/sf/antcontrib/antcontrib.properties"/>
<property name="src.dir" value="src" />
<target name="default">
<path id="path">
<dirset dir="${src.dir}" />
</path>
<property name="dirs" refid="path"/>
<foreach list="${dirs}" target="-echo" param="dir"
delimiter="${path.separator}"/>
</target>
<target name="-echo">
<echo message="Processing ${dir}" />
</target>
</project>
