RE: How to detect missing files when copying from a list of files ?

[Steve Allan <st...@wrq.com>]

EJ,

Thanks for the reply.  Sorry if I wasn't clear before - here's an example of
what I want to do.  Say I have a file called files.lst in the root of my
build with the contents:

 lib/foo.jar
 conf/foo.xml

I want to have an Ant task that reads the contents of files.lst and copies
the files listed in it to another directory, say a staging directory.  So
after running the task, I'd now have

  lib/foo.jar 
  conf/foo.xml
  stage/lib/foo.jar
  stage/conf/foo.xml

I want that task to fail if any either foo.jar or foo.xml is missing.  This
is a greatly simplified version; the real application might involve a
file.lst with hundreds of files explicitly listed.

You confirmed my observation that feeding a fileset to copy via the
includesfile element won't work.  Is there some other way to do this short
of <script> or exec'ing an external perl/shell script?

Thanks.
