Re: Failed to execute task move in Windows

Rhino Wed, 10 May 2006 12:30:40 -0700

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 movetask warning that the file will be deleted in these circumstances but I'd bea LOT happier if this behaviour were FIXED, not just noted. It certainlyfeels like a bug - and a very serious one! - to me. Deleting a fileunexpectedly could be catastrophic. Just imagine someone trying to renamethe Windows registry and deleting it instead!

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

I've not look at the code behind the move target...but I would guessit's java.io.File? If so...not sure why it would do that either<confused> ;)

Jeffrey,
 Thank you for the insight: you are absolutely right!

I'm still a bit mystified though. When my target and property were setlike this:<property name="path" value="C:\Documents andSettings\Administrator\Desktop" description="Path to jar which is to berenamed"/>

<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 Ichecked the directory, the jar file had been DELETED!! What's that allabout? I could see the rename failing but why would Ant and/or WindowsDELETE the file??--Rhino

    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).
