It depends ...

• The Ant process doesn't have enough permissions to delete the files (typically because they were created by a different user, perhaps a system user). Try running your Ant script as an administrative user, using Run As.
• Windows is really bad at cleaning up file locks when processes die or are killed; consequently, Windows thinks the file is locked by a process that died (or was killed). There's nothing you can do in this situation other than reboot.
• Get better tools to inspect your system state. I recommend downloading the SysInternals tools and using them instead of the default Windows equivalents.
