ANT FTP will not download a file if it is a symlink





------- Additional Comments From Bill@Explosivo.com  2002-11-08 20:06 -------
This does not mirror the functionality of command line FTP utilities which will 
download a symlink to a file.

I finally had a chance to peek into the source code and found where the problem 
is...  In org.apache.tools.ant.taskdefs.optional.net.FTP.java (Thanks for the 
tip Gus)

For a symlink the FTPFile will return false for both isFile and isDirectory...  
These are the only flags that get checked, so anything that comes back as a 
symlink (isSymbolicLink = true) is not counted or looked at.

Its easy enough to add in the code to include the symlink

Just change:

if (file.isFile()) {
     String name = vpath + file.getName();

to

if (file.isFile() || file.isSymbolicLink()) {
     String name = vpath + file.getName();

Now this brings out another problem...  Symlinks to a directory.  These do not 
register as directories.  You can get the linked to name by FTPFile.getLink() 
but this is string for the filename, not another FTPFile object.

I am still working on it, and most likely will need to get a file object for 
the target to see if its a directory... If so, it may need to be followed 
depending on how the decend into directories is done...

Any thoughts would be appreciated

I would guess that pattern matching should only happen against the link name, 
not the target...
