Several things:
1) First, I realized the escaping of $ is wrong... The property replacement
code of Ant will run without caring about the backslash, which ends up being
passed as is to the regex engine. I still think though that one needs to
escape the file separator for Windows, since it's the escape character of
the regex pattern.
2) Second, I looked at Uptodate.java, and unlike other tasks, it passes an
absolute path name (local platform file separator) to the mapper (calls
File#getAbsolutePath())
3) The replaced path name can use forward slashes instead of backslashes to
simplify the to pattern (java.io.File deals with a mix of slashes just fine)
<!-- RegexFileSeparator -->
<property name="rfs" value="\\"/> <!-- Windows -->
<property name="rfs" value="/" /> <!-- Unix - IGNORED HERE -->
<property name="srcfiles.dir" location="${topdir}/src"/>
<path id="targetfiles.path">
<pathelement location="${topdir}/subdir" />
</path>
<pathconvert property="targetfiles.dir" targetos="unix"
refid="targetfiles.path" />
<uptodate>
<srcfiles dir="${srcfiles.dir}">
<include name="beandir/com/foo/server/**/*Bean.java" />
</srcfiles>
<mapper type="regexp"
from=".*${rfs}beandir${rfs}(.*)${rfs}server${rfs}(.*)Bean.java"
to="${targetfiles.dir}/\1/spi/\2Local.java" />
</uptodate>
Maybe this time this will work, but somehow I doubt it... --DD

Nope, it doesn't work. Tried it before and tried it again just now.
