1) when we re-build derby once it has already been built, then we need to manually remove all the jar files ffrom the ..\sane folder otherwise during building jars (ant buildjars), it fails to progress as it is unable to overwrite the existing jars. I don't know that if it is supposed to behave so then why or does it depend upon the platform in some way ?
I've seen this problem, and used the same workaround. I think that it has something to do with having your source tree jars in your CLASSPATH when you perform the build. Since they are in your CLASSPATH, they are automatically opened by Ant during the build, and hence are in use and cannot be deleted. thanks, bryan
