Copy and Replace
I need to copy files into a new directory, and I'd like to perform a replace
on various string values they might contain in the process.
Since the Replace task is a fileset, I'm pretty sure I can pass that as an
argument to the copy task. However, will the copy occur without actually
changing the original files? Or does the replace happen on the original
files prior to the copy occuring?
To accomplish what I'm after, do I need to do it in two steps: copy, then
replace?
Thanks,
Christian

Don't think you can ever get rid of a filter, but you can reassign what
the filter value should be. Eg:
<target name="copy">
<filter token="foo" value="bar"/>
<copy file="foo" tofile="bar" filtering="yes"/>
<filter token="foo" value="baz"/>
<copy file="foo" tofile="baz" filtering="yes"/>
</target>

Looking at the documentation on filtering, I see the following example:
<filter token="year" value="2000"/>
<copy todir="${dest.dir}" filtering="true">
<fileset dir="${src.dir}"/>
</copy>
What I'm wondering is this: what if I have a different copy which needs to
use different filters? Is there any way to set up the filters, perform the
copy, and then remove the filters as soon as I'm done?
Thanks,
Christian

You can do a copy/replace in one step without affecting the original file
like this:
<copy file="web.xml" filtering="true" todir="${build.dir}"/>
Use the <filter> task to set up the replacement strings and tokenize your
source file with the appropriate format (see the <filter> and <copy>
documentation for more details).

Sorry for the duplication... I guess Diane and I are playing dueling helpers
today! She won this one, and I think I beat her to the zero-file length
answer! :)

<replace> is used to change a file in-place; use <filter> + <copy> with
filtering="on" to modify a file during a copy.
