Strange property bug
Hi,
I am using <propertyfile> together with <property> to have a counter
that will save the number between invocations of ant. This has worked
for a year, but now it has an off by one error. My guess is that this
is a bug in 1.8.0 (I am using the current Debian unstable version).
The problem is that new.test.number is read as 2 when there is a 3 in
the properties file. It is show in the log I have pasted in the bottom
of this message.
Is this a bug?
Is it in the bug tracker?
Can anyone suggest a workaround that also will work with ant 1.7?
Regards,
Kim Hansen
