task to 'cp -r --reply=no'
What task is the equivalent of 'cp -r --reply=no'. This command
recursively copies files and if the file exists in the destination,
skip copying that file and continue.

Ahh... yes, my test didn't bother specifying an
includes attribute, so I defaulted to "**/*". :)

it's simply a question of the fileset include pattern
if used
includes="**/*" =
main:
[echo] Files to copy =
[copy] Copied 1 empty directory to 1 empty directory under J:\copyto
so if i want to include empty dirs i use the pattern
includes="**/*" and need to exclude all the stuff i don't need,
i.e. excludes="**/*.bak, *.log"

Nice :-)
before =
J:\copyfrom\subdir1\
J:\copyfrom\subdir1\build.xml
J:\copyfrom\subdir2\
J:\copyfrom\subdir2\subsub2\build.xml
J:\copyfrom\build.xml
and
J:\copyto is a blank directory
with =
<?xml version="1.0"?>
<project name="bla" default="main">
<target name="init">
<fileset dir="J:/copyfrom" includes="**/*.xml" id="newfiles">
<present present="srconly" targetdir="J:/copyto"/>
</fileset>
</target>
<target name="main" depends="init">
<echo>
Files to copy = ${line.separator}${toString:newfiles}
</echo>
<copy todir="J:/copyto">
<fileset refid="newfiles"/>
</copy>
</target>
</project>
first run =
Buildfile: J:\eclipse_3_2\workspace\AntTest\test.xml
init:
main:
[echo] Files to copy =
[echo] build.xml;subdir1\build.xml;subdir2\subsub2\build.xml
[copy] Copying 3 files to J:\copyto
BUILD SUCCESSFUL
Total time: 891 milliseconds
the blank directory gets filled with meat =
J:\copyto\subdir1\
J:\copyto\subdir1\build.xml
J:\copyto\subdir2\
J:\copyto\subdir2\subsub2\build.xml
J:\copyto\build.xml
second run =
Buildfile: J:\eclipse_3_2\workspace\AntTest\test.xml
init:
main:
[echo] Files to copy =
BUILD SUCCESSFUL
Total time: 516 milliseconds
so no files are copied, as already present in targetdir ...
Blank directorie are not copied, how to achieve that if wanted ?
(manual says <cop<> task is set to ncludeEmptyDirs="true" ?

Hi Chris:
Try using a <present present="srconly" ... />
selector with your source <fileset>.

That's fine for one file, but cp -r tranverses a directory tree of
1000's of files. What's the ant equivalent of cp -r --reply=no?

The copy task states "By default, files are only copied if the source
file is newer than the destination file, or when the destination file
does not exist", but in my case I only want to copy files if "the
destination file does not exist".
