Jeffrey,

Thank you for the insight: you are absolutely right!

I'm still a bit mystified though. When my target and property were set like this:

<property name="path" value="C:\Documents and Settings\Administrator\Desktop" description="Path to jar which is to be renamed"/>

<target name="rename" description="Rename file.">
<move file="${path}\bi.jar" tofile="${path}\Bi.jar" />
</target>

the task failed and claimed that bi.jar could not be found; when I checked the directory, the jar file had been DELETED!! What's that all about? I could see the rename failing but why would Ant and/or Windows DELETE the file?

I've not look at the code behind the move targetbut I would guess
it's java.io.File? If sonot sure why it would do that either
<confused;)

Ahyeahright :|

Well the world would be a better place if everyone just ran Linux ;)

The problem is that the move task delete the destination before moving
the file, so I let you guess what happens in this case.

Windows file systems are case-insensitive while being
case-preserving; if all you want to do is to change the case
you'll need to use an intermediate file (i.e. move to temp_Bi.jar,
then move to Bi.jar).

Thank you for shedding light on this, Anthony!

Now I understand why the file disappeared.

At the very least, there should be a big note in the article for the move
task warning that the file will be deleted in these circumstances but I'd be
a LT happier if this behaviour were FIXED, not just noted. It certainly
feels like a bug - and a very serious one! - to me. Deleting a file
unexpectedly could be catastrophic. Just imagine someone trying to rename
the Windows registry and deleting it instead!
