For the last couple of days, I have not been able to access the JBT 3 nightly update site from eclipse updates. If I do directly to the site at http://download.jboss.org/jbosstools/updates/nightly/trunk/ there is a page with links to the updates, but clicking on any of them results in a Not Found message, for example:
The requested URL /jbosstools/updates/nightly/trunk/features/org.jboss.tools.seam.feature_3.0.0.CR2-N200901091812.jar was not found on this server.
we are looking into it - the builds have been failing in the last step the last few days.
