Description

This works on windows, but with a scanIntervalSeconds of 10 I always get this when it attempts to restart the webapp:

:WARN: failed ContextHandler@6ea3fe

I know this was a known issue if the file changes while it is being deployed, but the file is never mid change when this happens, and it happens on every deploy.

Is it possible that it is because the file is open when it is copied over?

If there is nothing that can be done here in place, I'd suggest copying the jars to a temp location before adding them to the webapp, then monitoring the originals for modification and copying them again between the stop and start of the webapp.

wdyt?

Does this happen on the very first deploy? What changed that initiated the redploy? Was it the maven-repository-configuration jar itself or something else?

no, its fine on the first deploy. It only happens on redeploy initiated by a change to one of the dependencies (in this case, maven-repository-configuration). The file is not mid-change when this happens.

Brett, I've checked in some changes to turn off URLConnection caching which has been associated with this problem (at least according to Google). Can you update your checkout of jetty to rev 845, rebuild and test for me? thanks.

Ok Brett, I've turned off even more caching on url connections. Can you svn update to 854 and try again? thanks.

Brett, could I ask you to svn update one more time and retest? I've changed it so that the url caching setting is only turned off for the maven plugin rather than for the whole of jetty. svn rev is 860.Thanks!
