Subject Problem deleting a file
Date Thu, 14 Jul 2011 16:37:34 GMT
Hi,

I'm using ant 1.8.2 on Windows 7/64 bit

One of the tasks in my build script deletes a target file before it is 
rebuilt.
The trouble is the file doesn't actually seem to get deleted until after 
ant exits.
This causes ant to generate an error when it tries to create the new 
version of the file.

Below is the relevant bit of the build script in case there is something 
I'm doing wrong.
The file in question is Quentin.jar. If I have a window open on the 
directory containing
this file, I can see it doesn't get deleted until after ant exits. When 
this happens, ant
fails with the error

idl_compile:
     [echo] Creating Quentin JAR
      [jar] Building jar: P:\Quentin\Manager\Java\tmp\Quentin.jar
     [move] Moving 1 file to P:\Quentin\Manager\Java\jars

BUILD FAILED
P:\Quentin\Manager\build.xml:459: Failed to copy 
P:\Quentin\Manager\Java\tmp\Quentin.jar to 
P:\Quentin\Manager\Java\jars\Quentin.jar due to 
P:\Quentin\Manager\Java\jars\Quentin.jar (Access is denied)

Any help would be much appreciated

Regards

Andy Ling
