how to supress unwanted deletion of files on publishing? [message #997673]

Our webapp creates files during startup and running which are not part of the eclipse project. These files are highly dynamic and therefor they can't be integrated
into the project.

During (auto)publish these files get deleted in tomcat and our app runs into inconsistencies.

I can't imagine there is no way to avoid this - but I can't find it either.

However, is this possible?

Publishing is responsible synchronizing the published webapp with what
is in your project. If a file exists in the published webapp, it is
assumed that it existed in your project and was deleted. Therefore, it
needs to be deleted from the published webapp. I don't know any
practical way around this required behavior.

However, it might work to enable Tomcat's "anti-resource locking"
feature. I think this works by making a separate copy of the webapp and
serves the copy to avoid locking files in the original webapp. If this
is accurate, it would prevent publishing from seeing your dynamically
created files. It does imply that if a change is made in the project,
the webapp will have to be reloaded or Tomcat restarted before any
published change will be copied to the separate copy that gets served.

Cheers,
Larry

I created a batch file which copied the "live" files into the
appropriate "development" directory. I then added the batch file to the
projects properties/builders, and made sure it ran before the publish

So the sequence of events is:
- copy the files
- publish deletes the files
- publish "sees" the files and then copies them over

Yes, it is redundant, but it gets around the issue
