You do the rm after ant fails right?

How is this file generated? Is it generated by the 'inofficial'
propertyFile-task which was send to the list? This gave me some trouble too,
but if you use the modified Version I mailed to you then it may work (I had
the same problems, seems to be too much file activity for windows somehow).

If it's not the propertyFile-task you may try to change 'loadFile' in as follows:

    private void loadFile (File file) throws BuildException {
        Properties props = new Properties();
        log("Loading " + file.getAbsolutePath(), Project.MSG_VERBOSE);
        try {
            if (file.exists())

                FileInputStream fis = new FileInputStream(file);
            } else {
                log("Unable to find " + file.getAbsolutePath(),
        } catch(Exception ex) {
            throw new BuildException(ex.getMessage(), ex, location);

I'm not sure what Java is 'required to do' if you use something like
'props.load(new FileInputStream(file));' - it can immediately close the file
after loading, but will it do in all cases?

If this does not help also you may want (maybe) try to use the included
'sleep'task just before the delete?

Example usage:

   <taskdef name="sleep"

   <target name="default">
     <echo message="1"/>
     <sleep seconds="5" gc="true"/>
     <echo message="2"/>
